This paper studies the algorithm of the adjustment level of the digital signal obtained by a quantization of the realization of a random process. The algorithm of adjusting the level uses a priori estimates of the probabilities of transition from one signal level to another and the probability of erroneous reception of bits. The influence of the inaccuracies of estimating the probability of erroneous reception of bits on the reliability level increases. The work consists of three sections. In section 1 is the implementation of a simulation model of obtaining realizations of a Gaussian random process with exponential autocorrelation function, its quantization, binary coding, binary phase modulation, demodulation and decoding. In section 2 is the implementation of the algorithm was to adjust the level of the digital signal, based on the knowledge of the probabilities of transition from one signal level to another and the probability of erroneous reception of bits. In section 3 we study the influence of accuracy of the knowledge of the probability of erroneous reception of bits on the efficiency of the algorithm for adjusting the signal level.
