FIELD: radio engineering, possible use in systems for transmitting discrete messages through channels with impulse interferences. ^ SUBSTANCE: in accordance to the method, multi-channel processing is performed, which includes filtration in time area by a block of filtration functions with following signal spectrum computation and calculation of instant frequency and entropy, then decision is made on basis of representation of produced two-parameter estimates (frequency-entropy) in polar system of coordinates with following transformation and restoration of a signal, making it possible to exclude sections which are subject to effect of impulse interferences and to perform averaging across remaining sections. ^ EFFECT: increased interference resistance of message receipt under conditions of influence of impulse interferences. ^ 3 dwg |
