FIELD: radio engineering.
SUBSTANCE: method of digital filtration by using adaptive, smoothing polynomial and wavelet filtration is characterised by the fact that input signal is processed simultaneously with all the above methods; at that, filtration quality with various algorithms is evaluated by calculation of correlation coefficient 
between all pairs of filtered signals as per the principle "each with each"; output signal output is formed, which represents the average value between two output signals the correlation coefficient between which is higher, and it is used for correction of filtration algorithms of composite filter at the next filtration step.
EFFECT: considerable interference immunity gain.
