METHOD FOR ADAPTIVE SELECTION OF AN OPTIMAL PARAMETER OF A CORRECTION ALGORITHM BASED ON THE RECEPTION OF THE WHOLE INFORMATION SIGNAL Russian patent published in 2019 - IPC H03H21/00 

FIELD: communication equipment.

SUBSTANCE: invention relates to a communication equipment and can be used in data communication systems with adaptive signal correction for selecting a parameter of the correction algorithm. Using algorithm based on received test signal u₀(t) calculating impulse response of correcting filter h_cor(t,α), by means of impulse response of correcting filter h_cor(t,α), using algorithm correcting information signal u_m(t) with phase manipulation, carrying N information symbols, resulting in obtaining corrected information signal K_m(t,α), which is symbol-by-demodulated to obtain a bit sequence b(n,α), n=1…N, bit sequence b(n,α), n-1…N is modulated to obtain a calculating a correlation coefficient after which Q dependence on parameter α is determined, by changing value of this parameter, resulting in optimum value of parameter α_opt, corresponding to maximum Q.

EFFECT: high accuracy of estimating the optimum value of a correction algorithm, selecting an optimum parameter of the correction algorithm based on analysis of phase spread of the corrected information signal of signals, without knowledge of a priori information on noise power, the signal / noise ratio and the corrected information signal.
