The adaptation method of a corrector of the intersymbol interference based on statistics of the third order is offered. This method is more noise-resistant than gradient method of adaptation which widely applied now if we use an asymmetric training signal. Using of developed method for updating coefficients of a corrector of an intersymbol interference in SDSL data transmission system allows to reduce a necessary signal-noise ratio in a adaptation mode by 1.6-3.2 dB at insignificant complication of a convolution coder.References
