INCOHERENT SHAPER OF ENVELOPE OF PSEUDO-NOISE PHASE-MANIPULATED SIGNAL Russian patent published in 2011 - IPC H04L27/22 

Abstract RU 2411678 C2

FIELD: radio engineering.

SUBSTANCE: incoherent shaper of envelope of pseudo-noise phase manipulated signal makes it possible for signals searching (before receiving route locks in synchronism by carrier) to formulate envelope of input signal and to practically unlimitedly increase time of coherent accumulation of signal with expected code as if its frequency is invariable and absolutely known. Incoherent shaper comprises incoherent heterodyne (4), phase-shift (90°) circuit (2), the first and second frequency mixers (1, 3), the first and second filters of intermediate frequency (5, 6), the first and second binary quantisers (7, 9), the first logical circuit "Exclusive OR" (8), logical circuits "OR" (10), "AND" (11), count trigger (12) and second logic circuit 'Exclusive OR" (13).

EFFECT: increased sensitivity in mode of signals searching with expected codes.
