METHOD OF PROCESSING PSEUDONOISE SIGNAL AND DEVICE FOR IMPLEMENTING THIS METHOD Russian patent published in 2008 - IPC G06F17/15 G06G7/19 

FIELD: physics; radio-technology.

SUBSTANCE: invention pertains to radio-technology, and particularly to optimum receiving of pseudonoise signals. The technical outcome is the increased resistance to interference of the output signal. According to the method, the radio frequency oscillation is converted to the video frequency range. The signal envelope is separated, sampled on time and amplitude on two levels, "1" and "0". The obtained code is recorded in an n-bit shift register of a discrete matched filter, matched by a direct code, and a discrete matched filter, matched by an inverse code. The automatic correlation function of the received signal is generated by removing the constant component from the result of adding output signals of the indicated discrete matched filters. The device which implements the method consists of a multiplier (1), low-pass filter (2), bidirectional limiter (3), cascade for coinciding with "1" (4), cascade for coinciding with "0" (8), inverter (7), n-bit shift registers (5,9), n-input adders (6,10), dual input adder (11), device for removing constant component (12), polling clock pulse source (T). At the first n-bit shift register and the first n-input adder there is discrete filter, matched by a direct signal code, and at the second n-bit shift register and the second n-input adder there is a discrete filter, matched by an inverse signal code.

EFFECT: increased resistance to interference of the output signal.
