Electronics Nuclear engineering HE Transportation and Communications The goal for the next generation of mobile communications system is to seamlessly integrate a wide variety of communication services such as high speed data, video and multimedia traffic as well as voice signals.

In this project, bit error rate simulation was carried out to study different 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. Important parameters are selected and their influences on rake receiver performance are investigated by means of simulations. Performance improvement due to rake receiver important parameters are studied. This project was implemented by using Matlab Simulink 7.0. Bit-error-rate (BER) performance tradeoffs between spreading factor, type of channel, and the number of Rake fingers that can be exploited for other application other than mobile phones or wireless LAN are presented at the end of the project.
