FIELD: radio engineering, namely, technology for synchronization of pseudo-random sequences, possible use for synchronization in case of low signal/noise ratio at receiver input.
SUBSTANCE: method for synchronization of pseudo-random sequence includes producing corrected value of information signal by means of analog processing of discrete counts of information signal with consideration of more precisely determined predicted value of signal, produced on basis of recurrent transformation of previously received and estimated information signals. Device for synchronization of pseudo-random series contains a digitizer, clock frequency extractor, corrector, first commutator, second commutator, block of analog delay lines, quantizer block, block of digital delay lines, control block, generator of supporting code series, generator of supporting signal, digital nonlinear complication unit, block for generating more precisely determined predicted value.
EFFECT: reduced time needed to enter synchronism due to improved precision of estimate of single element of pseudo-random sequence.
