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 taud1=K1tauc divisible by period tauc, total voltage is singled out, multiplied with received signal, delayed for time taud2=K2tauc, divisible by clock period tauc, voltage of frequency difference is singled out, multiplied with received signal, delayed for time tau, 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. ^ 2 dwg |
