摘要

A method for estimating a phase response for an upstream area in a channel is based on an extrapolation and, following forcible distortion of an amplitude response, coefficients of a time domain equalizer and coefficients of a channel target circuit are determined using a minimum MSE algorithm. When the cost function of a minimum MES is determined, the square of the coefficients of the time domain equalizer are included for determining the cost function in order to reduce the probability that the coefficients of the time domain equalizer diverge. A channel-shortening effect of the time domain equalizer is improved to reduce inter-symbol interference (ISI) and inter-channel interference (ICI). As a result, a signal to noise ratio (SNR) of a communication system is improved.
