A method is provided of updating an estimated channel impulse response of a maximum likelihood sequence estimator within a radio receiver (12 and 13). The method includes the steps of computing a rate of change of a channel impulse response from a current estimated channel impulse response and a previous estimated channel impulse response, selecting an update step size as a function of the rate of change of the estimated channel impulse response, and updating the estimated channel impulse response of the maximum likelihood sequence estimator based upon the selected step size. Apparatus is also provided of practicing the method in receiving and decoding a signal.

Method and apparatus of adaptive maximum likelihood sequence estimation

A method and apparatus are provided for maximum likelihood sequence estimation. The method and apparatus includes a first maximum likelihood sequence estimator signal path for flat fading and an at least second maximum likelihood sequence estimator signal path for other than flat fading. The method and apparatus for further includes selecting the signal path with a least relative magnitude mean square error.
