PROCESS OF TRANSMISSION AND RECEPTION OF INFORMATION WITH CODE COMPRESSION OF SIGNALS Russian patent published in 1994 - IPC

FIELD: information transmission equipment. SUBSTANCE: in process of transmission of information with code compression of signals formation of i-th (where i = 1...N) orthogonal combination at transmitting side is performed by delay of starting combination by (i-1)(1-1)τ, where t is length of element of combination which has no side overshoots in aperiodic autocorrelation function. In this case i-th modulating information sequence is also delayed by (i-1)(1-1)τ, where i = 1...N. That is why at receiving side only aperiodic autocorrelation function of one and same code combination is defined with reception of each information element which simplifies reception of information. Thanks to formation of orthogonal combinations by shift of copy of one starting code combination in clock periods no cyclic synchronization is required which enhances accuracy of reception of information. EFFECT: simplified process of reception, enhanced accuracy of it. 5 dwg
