AUTOCORRELATIVE DECODER OF PSEUDONOISE SIGNALS WITH DIFFERENTIAL PHASE SHIFT KEYING Russian patent published in 2018 - IPC H04L27/22 H03D3/02 

FIELD: communication equipment.

SUBSTANCE: invention relates to telecommunications techniques and can be applied to the processing of discrete signals with differential phase shift keying in systems with pseudonoise signals in conditions of organized (deliberate) interference. Device comprises first 1 and second 2 delay elements, first multipliers 3, 4, 5, integrators 6, 7, 8, second multipliers 9, 10, 11, inverters 12, 13, 14, synchronization unit 15 with a pseudorandom sequence generator, third delay element 16, third multiplier 17, first 18, second 19, third 20 and fourth 21 totalizers, maximum signal selection unit 22, summing accumulator 23, decision unit 24.

EFFECT: increase noise immunity of receiving signals with differential phase shift keying due to the use of pseudonoise transformations of signals that make it impossible to create an effective interference for the violation of the signal reception process, and at the expense of an additional increase in the energy of the signal by its accumulation with an extension of the processing interval from two to three signal transmissions.
