DIGITAL NON-COHERENT DEMODULATOR OF FOUR-POSITION SIGNALS WITH RELATIVE PHASE MANIPULATION Russian patent published in 2018 - IPC H04B1/10 H04L27/233 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to the field of radio engineering and can be used in digital information signal reception devices for digital non-coherent demodulation of four-position signals with relative phase shift keying (QPSK). Digital non-coherent demodulator of four-position signals with relative phase shift keying contains an analog-to-digital converter, the shift register of multi-digit codes for four samples, the first and second n-cascaded quadrature signal processing channels, the clock generator, the first and second register memories, first, second, third and fourth digital multipliers, first and second adders, first and second subtractors, first and second decoders and decoders.

EFFECT: providing high-speed digital demodulation of signals with four-position relative phase shift keying.
