FIELD: radio engineering.
SUBSTANCE: method includes multiplying received signal with support signal, duration of received signal is measured, frequency detection of received signal is performed, to separate moments of jump-like change of phase, number and value of clock periods is determined, support signal is formed by delaying received signal for time τd1=K1τc divisible by period τc, total voltage is singled out, multiplied with received signal, delayed for time τd2=K2τc, divisible by clock period τc, voltage of frequency difference is singled out, multiplied with received signal, delayed for time τ, which is periodically changed on basis of linear law, low-frequency voltage is singled out, proportional to autocorrelation function, and compared to threshold level, if threshold level is exceeded, cyclic displacement is measured, on basis of which code structure of received signal is determined.
EFFECT: higher efficiency.
