Performance Evaluation of Rake Receiver using Rayleigh Fading Channel in Terms of Bit Error Rate

The fastest-growing sector of the communications is wireless communication. Yet, the wireless environment is quite unstable, and fading is the main disadvantage. Several pathways are taken by the signal as it moves from the transmitter end to the receiver end. This causes the transmit signals to be received at the receiver in numerous versions, which results in multipath propagation. There will be variations in the attenuations, phases, and travel delays of each of these signals. By combining them with a Rake Receiver, this issue can be resolved. It is a radio receiver created with the intention of reducing multipath fading’s negative impacts. Rake receiver employs several fingers, sometimes referred as correlators, to individually identify the M strongest multipath components. Each received signal is corrected for delays before being fed to the combiner and equalizer. The weighted outputs of the M correlators are then used to determine demodulation and bit decisions. Using Bit Error Rate, this technique’s performance will be assessed.
