ABSTRACT:
A decision feedback equalizer (DFE) processes a signal having multiple code channels by filtering an error signal based on a difference between a received signal and an estimated received signal. The received signal is processed to recover data on each of the code channels and to generate an estimate of a transmitted signal corresponding to the received signal. A channel estimate is applied to the resulting estimated transmitted signal to generate the estimated received signal. After the filter filters the error signal, a combiner combines the filtered error signal and the estimated transmitted signal.
