OPTIMAL INCOHERENT RECEIVER WITH PHASE-MANIPULATED SIGNAL Russian patent published in 2021 - IPC H04L27/233 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering and can be used in information transmission systems. In an optimal incoherent receiver of a phase-manipulated signal, the implementation of the corresponding detectors in the form of an adder, the first and second subtraction blocks implements total-difference processing and ensures the formation of matched filters from the output signals at the two inputs of the first intersection block (in the first channel) and at two inputs of the second intersection block (in the second channel), signals with the maximum number of mutually antiphase peaks of ACF and ICF. The presence of the first and second intersection blocks provides mutual compensation of ACF, ICF, noise and interference peaks by using the property of choosing the smaller of the compared input values inherent in the intersection procedure. At the outputs of the first and second low-pass filters, the envelopes of the output signals of the intersection blocks are allocated in the channels.

EFFECT: decrease in the number and level of lateral peaks of the autocorrelation function (ACF) of the phase-manipulated signal in the main channel, a decrease in the level of peaks of the intercorrelation function (ICF) in the orthogonal channel and a decrease in the relative level of noise and interference in the channels.
