Design and Simulation of Detection Guided Rake Receiver with Improved SNR and Low Bit Error Rate

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.
