ABSTRACT:
An adaptive equalizer which has a decision feedback adaptive equalizer and linear adaptive equalizer. A delay measuring circuit recieves an incoming signal and determines a multipath propagation characteristic for a channel. The delay measuring circuit includes a correlator which outputs a signal based upon a direct wave and a delay wave. Selection of the decision feedback adaptive equalizer or the linear adaptive equalizer is based upon the maximum delay time of the delay wave as determiend by the delay measuring circuit.
