FIELD: information technologies. ^ SUBSTANCE: in method all versions of signals are detained in demodulator with the help of discrete detaining lines designed for maximum possible number of elements of code combination, and having taps arranged periodically along detaining line via number of elements contained in a single code combination. At the outlet of each tap in each line code combinations are checked for availability of errors in them. Number of correct code combinations is identified, which border with each other in detaining lines from according taps to ends of detaining lines. For each subsequent code combination prior to its delivery to decoder, all numbers are compared, which were produced in the range of code combination duration. Maximum number is used to select detaining line and make decision on starting of cyclic decoder synchronisation cycle. From the outlet of selected detaining line subsequent code combination with cycle start is sent to decoder, and in case if in two or more counters at this moment of time maximum results are same, then another code combination is sent to decoder from the outlet of that delay line, from which previous code combination was sent. ^ EFFECT: invention provides for determination of correct values of initial phases for detection of errors in code combination without additional redundancy. ^ 2 cl, 1 tbl, 4 dwg |
