Abstract

Изобретение относитс  к передаче и приему сигналов в оптическом диапазоне волн, а более конкретно - к устройствам оптимального приема сигналов. Изобретение позвол ет повысить помехоустойчивость приема оптических сигналов с пассивной паузой за счет использовани  информации о средней мощности принимаемого сигнала и синтеза оптимальной структуры нек.оте рентного приемника. Дл  этого электрический сигнал с выхода фотодетектора 1 последовательно проходит черб квадратор 9 и интегратор 10, на выходе ко- торого получаетс  величина, равна  средней мощности принимаемого сигнала, котора  через усилитель 11с заданным коэффициентом усилени  поступает на вход сумматора 5, на другой вход которого поступает с выхода бесселевско-логарифмиче- ского усилител  4 величина, пропорциональна  огибающей результата оптимальной обработки принимаемого сигнала . Из этой суммы в вычитающем устрой стве 6 вычитываетс  заданна  константа от источника эталонного напр жени  8 и ре-, зультат сравниваетс  в пороговом устройств, ве 7 с кулевым порогом, при превышении порога принимаетс  решение о приеме Г, в противном случае - О. 1 й . с; feThe invention relates to the transmission and reception of signals in the optical wavelength range, and more particularly to devices for optimal reception of signals. The invention improves the noise immunity of receiving optical signals with a passive pause by using information on the average power of the received signal and synthesizing the optimal structure of a certain receiver. For this, the electric signal from the output of the photodetector 1 sequentially passes the flap of the quadrator 9 and the integrator 10, at the output of which a value is obtained, which is equal to the average power of the received signal, which through the amplifier 11c is supplied with the specified gain to the input of the adder 5, the other input of which comes from the output of the Bessel-logarithmic amplifier 4 is a value proportional to the envelope of the result of the optimal processing of the received signal. From this sum in the subtractor 6, the predetermined constant from the source of the reference voltage 8 is subtracted and the result is compared, the result is compared in the threshold devices, ve 7 with the coolant threshold, when the threshold is exceeded, a decision is made on the reception of G, otherwise - O. 1st . with; fe
