FIELD: communication system coders.
SUBSTANCE: for coding input information of k-bit sequence and generating code word in code-division multiple access communication system coder is provided to code input information using simplex code (r, k) and to generate sequence of code characters, r = 2^k - 1 long, repeater functions to repeat sequence of code characters t = N/r + 1 times, and punching device affords A = rt - N times punching in t repeated sequences of code characters so as to ensure length N of resultant codes.
EFFECT: reduced occurrence of errors in transferred information; enhanced measurement accuracy of data frame variable speed.
