DIGITAL ADAPTIVE CHANNEL EQUALIZER

摘要

A channel equalizer that compensates for signal distortion of a signal in a communication channel includes an equalization filter, which gain-equalizes a received signal received through the communication channel, and an equalization control circuit, which generates a gain control signal for controlling the gain of the equalization filter. The equalization control circuit specifies a phase switch in data obtained by the equalization filter as an isolated bit and generates the gain control signal based on a width of the isolated bit.
