In this paper, an algorithm for determining primary codec parameters of software-defined radio systems based on correlation function of received signal is considered. The aim of the work is to develop an algo rithm for determining primary codecs parameters. The results of experimental studies on the assessment of autocorrelation functions for various types of transmitted data are presented. An algorithm for determining the parameters of primary codecs based on the analysis of correlation function maxima of the first, second, third and fourth order and determining the duration and structure of transmitted frame and, accordingly, primary coding algorithm based on the intervals between them is proposed. The performance of the pro posed algorithm is studied for different analysis intervals and under the influence of interference and distor tion with error probability in communication channel from 0 to 5 %.
