ABSTRACT:
A multi-branch receiver comprises a plurality of signal branches including branch filters to filter respective branch input signals and to produce corresponding branch output signals, a combiner to combine the branch output signals to produce a combined baseband signal, a pre-filter to filter the combined baseband signal to produce a received signal with minimum phase channel characteristics, and an equalizer to generate an estimate of a data sequence contained in the received signal.
