With the growing interest in integration of voice, data and video traffic in wireless communication networks, CDMA emerged as an attractive access technique. The performance of wireless system is deteriorated in presence of multipath fading environment. Hence, the error performance analysis is a fundamental requirement to deploy CDMA system. The Bit Error Rate (BER) is one of the error performance parameter in communication systems. This paper presents estimation of BER as function of Eb/No (bit energy to noise power spectral density ratio) using Monte Carlo simulation technique. The simulation includes the effects of Additive White Gaussian Noise, multipath and Multiple Access Interference (MAI). Direct Sequence Spread spectrum with BPSK modulation is used for the simulation. The Ricean fading channel with various factor K is considered. Results are presented in form of graphs which show the effect of different Ricean factor K on BER. These elegant results can be used for evaluating the system capacity, designing power control algorithms and appropriate channel coding techniques for CDMA.
