Abstract
1. System for the transmission and reception of digital information signals, especially for the digital transmission of sound by way of satellites, in which the data sequences are arranged following one another in time a block and in which in the receiver the block is divided in two timewise parallel part blocks (A, B) representing the data sequences, characterized in that each part block (A, B) exhibits a synchronisation word of an equal or equivalent type of equal length, that for the time recognition and if necessary for the compensation of the phase position of the part blocks (A, B) a correlator (3, 5, 7; 4, 6, 8; 3, 7, 14, 15, 44, 47-52) is used for each part block, that for the synchronisation code words are used which exhibit an unequivocal maximum of their autocorrelation function for the instant T = O, and that the auto correlation function for all instants T Not = O is effectively minimal.
