FIELD: communication equipment.
SUBSTANCE: invention relates to a communication equipment and can be applied to the processing of discrete signals with second-order differential phase shift keying in spread spectrum systems (with pseudorandom signals) at instability of the carrier frequency and in conditions of organized (intentional) interference. Device comprises first multiplier 1, synchronization unit 2 with a pseudorandom sequence generator, first delay element 3, second delay element 4, first phase shifter 5 on π/2, second phase shifter 6 on π/2, second multipliers 7, 8, fourth multipliers 9, 10, first integrators 11, 14, second integrators 12, 13, third multipliers 15, 16, adder 17, accumulator 18, decision block 19.
EFFECT: higher noise immunity of receiving signals with second-order differential phase shift keying by using pseudorandom signal transformations, which make it impossible to create an effective interfering signal for disturbing the process of receiving signals.
