RECIRCULATION CORRELATOR OF RESOLUTION OF PHASE-CODE MANIPULATED SIGNALS Russian patent published in 2006 - IPC H04L27/18 H04J13/00 

FIELD: radio engineering, possible use in radiolocation stations for allowing phase-code manipulated signals with approximately equal frequencies.

SUBSTANCE: input signal of device is an additive mixture of video-frequency phase-code manipulated signals with varying amplitudes and delays, encoded by M-series, digitized with temp in two counts on elementary analog quantization step in strobe M=4·n-1. By means of first adder and first shift register input signal by its recirculation amounts to interval, equal to 2·n. By means of first commutator signal is divided on even and odd series, which in turns pass to block of cross connections, then to block of fast Walsh transformation, and further to block of reverse check connections and second commutator. From the latter signals are sent to block for synchronization with elementary quantization step two counts long. Further signals are sent to third commutator, which in accordance to its evenness and oddness order sends them to second adder. By means of second adder and second shift register, signal from third commutator by its recirculation amounts to interval, equal to 2·n.

EFFECT: substantially decreased computer power costs due to recirculation transformation of input signals, making it possible to apply fast Walsh transformation.
