<p>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.</p> |
