Method and apparatus for equalization in a diversity receiver

摘要

A receiver having an adaptive maximum likelihood sequence (MLSE) estimator and method are provided, in particular in a nonlinear receiver, wherein a channel estimator is used to estimate the channel to be used in the MLSE estimator in order to minimize distortion. In the MLSE estimator, the channel estimation is extracted from the phase of the signal using a known training sequence pattern in the received data frame. The channel estimation is adaptively updated using a Least Mean Square (LMS) algorithm by applying tentative decision in the received signal.
