High speed data, particularly, direct sequence code-division multiple access (DS-CDMA) experiences inter symbol interference (ISI) in wireless communications due to delay differences of multipath propagations. Rake receiver is an effective method of recovery of baseband signal for wideband CDMA (WCDMA) under multipath environments. This paper deals with bit error rate (BER) performance of a Rake receiver for multipath wireless CDMA contaminated by additive white Gaussian noise (AWGN), and impact of fingers on reception of fading channel signal.
