An MMSE equalizer matrix update interval of 1 ms (high mobility) is achieved with less than 50% CPU utilization. Concurrent bidirectional processing (precoding and postprocessing) is shown to be feasible with this update rate.en3G mobile communicationequaliserleast-mean-squares methodmatrix algebramicroprocessor chipsmimo communicationofdm modulation621conference paper
