In Code Division Multiple Access (CDMA) system, there is a phenomenon where distortion of the signal occurs while propagating through wireless communication system caused by fading channel. Fading is a fluctuation in received signal's amplitude, phase and angle of arrival due to multipath reflective paths. The project is to simulate the transmission in three different fading channels, Additive White Noise Gaussian (A WGN), Rayleigh fading and Rician. The transmission will be implemented in both CDMA and WCDMA (additional of W for Wideband) in order to compare the performance between the two systems. The observation and evaluation is done over Bit Error Rate (BER) performance in these channels. To simulate for high data rate WCDMA system, Quadrature Phase Shift Keying (QPSK) modulation scheme is considered to modulate the signal. Computer simulation tool, MA TLAB, will be used throughout the research to distribute the signal and evaluate the BER performance. The simulation will be conducted using Simulink, a simulation method where a transmission system is create by setting up the appropriate blocks and its parameter. A study of BER performance in different fading channels is important to evaluate which fading channel gives the worst performance. Besides, the different technology and chip rate of CDMA and WCDMA systems makes a study in these systems is relevant for evaluation purpose.
