ABSTRACT:
An architecture for a rake receiver of a CMDA demodulator utilizes a common data path for signal processing. This common data path is shared by all channels (either physical channels or propagation paths within physical channels) to avoid redundant calculations, reduce circuit space and reduce power consumption. The sharing of the common data path for demodulation is made on a time divided manner, with each channel being given sequential access to the data path to perform all or part of a given demodulation function (for example, de-scrambling, de-spreading, de-rotating, and de-skewing accumulation).
