Abstract :
A parallel LMS-ADFE (least mean square-adaptive decision feedback equalization) scheme that allows the ADFE to adapt at every data point in parallel, so that local channel variation can be accurately tracked at a rate independent of hardware speeds, is proposed. Simulations show that this scheme displays tracking capability similar to that of the serial ADFE. Furthermore, the proposed ADFE algorithm can be parallelized with complexity linearly related to speedup
