Abstract

In the radio environment the multipath propagation causes the signal at the receiver to distort and fade significantly, leading to inter-symbol interference (ISI). Spread spectrum mobile communication systems use RAKE receivers to minimize the communication errors resulting from multipath effects. Simulations demonstrate that the developed detection guided RAKE receiver has a significant improvement in the signal-to-noise ratio (SNR), subsequently leading to a lower bit error rate and high signal to noise ratio than the current RAKE receiver with three correlators.
