Embodiment
Below, with reference to accompanying drawing, embodiments of the present invention are described.In addition, in the execution mode below, same structural element is paid prosign.
(first execution mode)
Fig. 1 is the block diagram of structure of the radio communication device of expression first execution mode of the present invention.The radio communication device of first execution mode is characterised in that to have: the transmission circuit that the CDMA pattern is used; A transmission circuit that TDMA uses of the frequency band identical in fact with the frequency band of above-mentioned CDMA pattern with use, the transtation mission circuit of above-mentioned two patterns is made of the transtation mission circuit of a system.Here, in the first embodiment,
(1) transmission frequency of using in the CDMA pattern for example is 824-849MHz, and its receive frequency for example is 869-894MHz;
(2) transmission frequency of using in the TDMA pattern for example is 824-849MHz, and its receive frequency for example is 869-894MHz.
In these two patterns, use identical frequency band in fact.
In Fig. 1, switch SW 1 is used to send the switching of reception and the selection of above-mentioned two patterns is switched.In addition, switch SW 2 is used for the selection switching of above-mentioned two patterns when sending.Further, low pass filter 12 is set to the wireless transmission signal of low-pass filtering TDMA pattern, and band pass filter 14 is set to the wireless receiving signal of bandpass filtering TDMA pattern.In addition, diplexer filter 13 has two band pass filter 13a, 13b, and above-mentioned band pass filter 13a, 13b are set to respectively the wireless transmission signal and the wireless receiving signal of bandpass filtering CDMA pattern selectively.
When the reception of CDMA pattern, switch SW 1 switches to contact b side.At this moment, the wireless receiving signal of the CDMA pattern that receives by antenna 11 is input to CDMA pattern receiving circuit 20 through the contact b of switch SW 1 and the band pass filter 13b of diplexer filter 13, CDMA pattern receiving circuit to the wireless receiving signal imported carry out the high frequency low noise amplify, to the processing of the frequency inverted of intermediate-freuqncy signal and demodulation etc., and the baseband signal of output after handling.Here, baseband signal is a modulated signals.
In addition, when the reception of TDMA pattern, switch SW 1 switches to contact c side.At this moment, the wireless receiving signal of the TDMA pattern that receives by antenna 11 is input to TDMA pattern receiving circuit 21 through the contact c and the band pass filter 14 of switch SW 1, wireless receiving signal that 21 pairs of TDMA pattern receiving circuits are imported carry out the high frequency low noise amplify, to the processing of the frequency inverted of intermediate-freuqncy signal and demodulation etc., and the baseband signal of output after handling.
Further, when the transmission of TDMA pattern, when switch SW 1 is switched to contact a side, switch SW 2 is switched to contact a side.At this moment, the baseband signal of answering wireless transmission is input to amplitude composition detection device 15 and phase component detector 16, amplitude composition detection device 15 uses for example method such as envelope detection method, from the baseband signal of being imported, detect the amplitude composition of baseband signal, and the amplitude that will represent this amplitude composition for example becomes sub-signal to output to have used in the power amplifier 19 of the band Modulation and Amplitude Modulation function of polar modulation method.Here, the power amplifier 19 of amplitude composition detection device 15 and band Modulation and Amplitude Modulation function constitutes the Modulation and Amplitude Modulation circuit.In addition, phase component detector 16 for example carries out amplitude, and detects the phase component of baseband signal from the baseband signal of being imported, and after the phase component signal of representing this phase component is carried out differential, outputs to voltage-controlled oscillator 17.Here, phase component detector 16 and voltage-controlled oscillator 17 constitute phase-modulation circuit.Voltage-controlled oscillator 17 is by according to the phase component voltage of signals level of being imported, the frequency of oscillation that sends carrier signal is changed, thereby generation phase modulated signal, and send the band pass filter 18 of signal component, and output in the power amplifier 19 of band Modulation and Amplitude Modulation function through bandpass filtering only.The power amplifier 19 of band Modulation and Amplitude Modulation function according to the amplitude from amplitude composition detection device 15 become sub-signal modulate and the amplitude of power amplification from the phase modulated signal of the transmission carrier signal of band pass filter 18 after, produce the wireless transmission signal.This wireless transmission signal is through the contact a side of the contact a of switch SW 2 side, low pass filter 12 and switch SW 1 and after being input to antenna 11, from antenna 11 emissions.
Further, when the transmission of CDMA pattern, when switch SW 1 is switched to contact b side, switch SW 2 is switched to contact b side.At this moment, though will answer the baseband signal of wireless transmission to be input to amplitude composition detection device 15 and phase component detector 16, be set to the output signal level from amplitude composition detection device 15 is set at 0 and do not carry out Modulation and Amplitude Modulation.Phase component detector 16 is identical with the TDMA pattern, detects the phase component of baseband signal from the baseband signal of being imported, and after the phase component signal of representing this phase component is carried out differential, outputs to voltage-controlled oscillator 17.And, voltage-controlled oscillator 17 is by according to the phase component voltage of signals level of being imported, the frequency of oscillation that sends carrier signal is changed, thereby generation phase modulated signal, and send the band pass filter 18 of signal component through bandpass filtering only, output in the power amplifier 19 of band Modulation and Amplitude Modulation function.The power amplifier 19 of band Modulation and Amplitude Modulation function is not as mentioned above, carry out Modulation and Amplitude Modulation, but behind the wireless transmission signal that power amplification is imported, produce the wireless transmission signal, this wireless transmission signal is after the contact b side through the band pass filter 13a of the contact b of switch SW 2 side, diplexer filter 13 and switch SW 1 is input to antenna 11, from antenna 11 emissions.
In this embodiment, when the transmission of TDMA pattern, send to use for example polar modulation method that made up Modulation and Amplitude Modulation and phase modulated and the wireless transmission signal of modulated mistake.On the other hand, when the transmission of CDMA pattern, transmission will be made as 0 from the signal of amplitude detector 15, only carry out phase modulated, the wireless transmission signal that for example uses the quadrature modulation method of QPSK modulation etc. to modulate.And the transmission in the CDMA pattern receives to be carried out on both direction simultaneously, that is, communicate by letter under full duplex.
In the wireless transmission circuit of the TDMA of prior art pattern, though band pass filter 18 generally is not set, but, in this case, phase modulated signal from voltage-controlled oscillator 17 is to have applied the signal after the phase modulated to sending carrier signal, in the frequency acceptance band of correspondence, has noise contribution as the side wave band composition outside the wireless transmission signal.In order to address this problem, the noise that needs to increase voltage-controlled oscillator 17 recently suppresses noise contribution, but thus, need make the level increase from the phase modulated signal of voltage-controlled oscillator 17.Thus, the current sinking of wireless transmission circuit increases.In order to address this problem, even when the transmission of TDMA pattern, the noise contribution in the time of also can using band pass filter 18 to remove phase modulated, the signal to noise ratio that can obtain wishing compared with prior art, can reduce current sinking.
Further, describe the task of above-mentioned band pass filter 18 below in detail.Owing in the CDMA pattern, carry out to send simultaneously and receive, make the noise of the frequency acceptance band in the minimum output signal that does not influence wireless transmission circuit when receiving input (, the input signal of wireless receiving circuit) so need be reduced to.But if will use the attenuation of the diplexer filter 13 increase frequency acceptance bands after power amplifier 19 outputs, then the loss of signal in the transmission frequency becomes big, especially makes by the big wireless transmission power dissipation after power amplifier 19 amplifications.Therefore, even the loss by the 18 wireless transmission signals of the band pass filter before the input terminal of power amplifier 19 becomes big a little, reduce the noise of frequency acceptance band by the attenuation of the big frequency acceptance band of abundant change, and loss before the input of power amplifier 19, just passable with less power loss, so as a result of can reduce consumed power.
In addition, do not send and receive though in the TDMA pattern, do not carry out simultaneously, but since have the noise of the frequency acceptance band when sending become for the disturbing wave of other radio communication devices outside self may, so identical with the CDMA pattern, need be reduced to the minimum reception input that makes the noise contribution of frequency acceptance band not have influence on the receiver of other radio communication devices.At this moment,, then can relax the size of the signal to noise ratio of voltage-controlled transmitter 17, thus, can obtain the reduction effect of consumed power as if the frequency acceptance band attenuation of getting the CDMA pattern of regulation by band pass filter 18.
In the above embodiment, though used band pass filter 18, but the present invention is not limited to this, from making the attenuation of the band component decay regulation outside the transmission frequency band that comprises frequency acceptance band, and the signal of the above-mentioned transmission frequency band of bandpass filtering and art-recognized meanings that it is passed through, for example can use the band stop filter of the band component decay outside the transmission frequency band that comprises frequency acceptance band or send relatively under the high situation of frequency band, also can use low pass filter at frequency acceptance band.In addition, on the contrary, send relatively under the low situation of frequency band, also can use high pass filter at frequency acceptance band.That is, also can replace band pass filter 18, have the filter of the signal component bandpass filtering that makes the wireless transmission signal.
According to first execution mode that as above constitutes like this, when the transmission of TDMA pattern, also can use band pass filter 18 to suppress the noise contribution in the wireless transmission signal and reduce current sinking.In addition,, so compared with prior art, can reduce circuit scale significantly owing to constituted the wireless transmission circuit of TDMA pattern and the wireless transmission circuit of CDMA pattern by the wireless transmission circuit of a system, can simplified structure.
(variation of first execution mode)

In Fig. 2, TDMA pattern receiving circuit 21 constitute have high frequency low noise amplifier 31, blender 32, intermediate-frequency circuit (below be called the IF circuit) 33 and demodulator 34.In addition, switch SW 3 switches to contact a side when the transmission of TDMA pattern and CDMA pattern, on the other hand, when the reception of TDMA pattern, switches to contact b side.
In TDMA pattern receiving circuit 21, after amplifying, be input to blender 32 by high frequency low noise amplifier 31 low noises from the wireless receiving signal of the TDMA pattern of band pass filter 14 output.Blender 32 is mixing the wireless receiving signal imported and from voltage-controlled oscillator 17 through the local oscillation signal of the contact b of switch SW 3 input and after having carried out the low frequency conversion, after removing composition outside the intermediate-freuqncy signals (below be called the IF signal) by IF circuit 33, the IF signal that amplifies after removing also outputs to demodulator 34.Further, demodulator 34 is exported after using the demodulation method of regulation that the IF signal of being imported is demodulated into baseband signal.
As above illustrated, variation according to first execution mode, except the action effect of first execution mode, by being used as the local oscillation signal of TDMA pattern receiving circuit 21 usefulness from the oscillator signal of voltage-controlled oscillator 17, the number of the oscillator of wireless receiving circuit can be subtracted 1, can simplify the structure of radio communication device.
