Abstract

An auto-coefficient renewal digital channel equalizer is disclosed, including an auto-coefficient renewing device for automatically renewing a coefficient using received data and an error signal, an error detecting device for detecting an error signal from a signal of the auto-coefficient renewing device, a device for determining convergence or divergence of the error signal detected in the error detecting device to produce a convergence or divergence signal according to a result of the determination, and an error processing device for shifting down the error signal detected in the error detecting device a certain number of bits in response to a convergence signal to produce a signal smaller than the received error signal to the auto-coefficient renewing device, thereby processing the coefficient renewal at the same rate with the data for all of the taps of an equalizer. The equalizer converges at an increased rate, and operation of the equalizer is made more stable even in diversion of a reception channel.
