Abstract
A RAKE receiver for use in a CDMA system is implemented as a transverse correlator in the complex domain. The transverse topology results in the correlator comprising a plurality of serial stages, each stage formed as a canonical unit of a multiplier, adder and memory. When implemented in the complex domain, the multiplier is replaced by multiplexers and the hardware may be significantly reduced by multiplexing between the I and Q components.
