English Abstract
-This project main target to study fading channel, and spreading factors on WCDMA and study the performance of rake receiver in terms of bit error rate through simulation by using MATLAB Simulink. As the first step in the design of a rake receiver, generated software prototype in MATLAB included a transmitter and a multipath Rayleigh fading channel, as well as a rake receiver with up to four fingers.
Using the software prototype, verified the functionality of all blocks of the rake receiver, estimated the performance in terms of bit error rate. The received signal at the WCDMA Receiver Antenna subsystem is the sum of attenuated and delayed versions of the transmitted signals due to the multipath propagation introduced by the channel.
At the receiver side, a RAKE receiver is implemented to resolve and compensate for such effect.
In this project, bit error rate simulation was carried out to study BPSK & QPSK modulation techniques, and the contribution of rake receiver in WCDMA system for the overall system performance.
Next, evaluation on the bit error rate for rake receiver at different conditions such as varying number of rake fingers, spreading factor, type of channel (Additive White Gaussian Noise (AWGN) and Rayleigh Fading Channel) are carried out
