ABSTRACT:
Demodulation is provided for a base station receiver in a cellular communication system by a demodulator having four data linked digital signal processors. An MLSE equalizer and maximal ratio combiner for diversity paths includes multiple components that are partitioned among the processors for pipelined execution with predetermined time ordering.
