Abstract :
This letter analytically determines the effects of selective diversity on the performance of a RAKE receiver in dense multipath channels featuring an arbitrary power delay profile. The approach devised permits assessing the symbol-error probability of the RAKE receiver with simple computations, and determining the influence on system behavior of different power delay profiles and number of resolved paths, as well as signal bandwidth.
