The complexity of the maximum likelihood sequence estimation (MLSE) prohibits its widespread applications on channel equalization. In the paper, a reduced complexity algorithm, the dynamic T-algorithm, is proposed to compensate for the intersymbol interference (ISI) introduced by wideband mobile radio channels. The bit error rate (BER) performance over a two-path Rayleigh faded channel having a 5 symbol period of excess delay is examined. The average number of survivors is reduced by more than 90% (i.e., when t=0.2) at an expense of 3 dB degradation when the BER is 10-2
