FIELD: communications engineering; computer networks with pseudorandom operating frequency tuning. SUBSTANCE: binary vector length of input signal block is chosen according to number of frequency channels used , two binary vectors of pseudorandom trains are shaped by simultaneously and concurrently picking information off different positions of shift register, transmitter is sequentially tuned to two carrier frequencies in compliance with codes, and during transmission signal, if any, is demodulated in each frequency channel, and signal in the form of binary vector corresponding to ordinal number of frequency channel is generated. EFFECT: enhanced noise immunity of communication link. 5 cl, 2 dwg
