Abstract
An adaptive equalizer includes a channel memory length estimator (,) for estimating a channel memory length of a received signal, an adaptive equalizer (,) for reducing effect of intersymbol interference on the received signal using a technique suitable for a channel with a fast time-varying characteristic, an adaptive equalizer (,) for reducing effect of intersymbol interference on the received signal using a technique suitable for a channel with a large delay spread, and a selector for switching, in response to the channel memory length supplied from the channel memory length estimator (,), between the adaptive equalizer (,) suitable for the channel with the fast time-varying characteristic and the adaptive equalizer (,) suitable for the channel with the large delay spread, thereby implementing good bit error rate performance.
