Abstract
An integrated demodulation processor used in a modem for a spread spectrum communications system despreads multipath receive signals then uses a time sliced transform processor to process the multiple signals in to a single series of soft decision results. The demodulation processor uses a single transform engine which operates on a time slice basis. The output of the processor engine cascade through a pipeline processor which, on a time slice basis, operates on signals corresponding to each multipath receive signal. The processed results are dual maxima decoded to provide soft decision data.
