In digital communication system, selection of the most appropriate access method is a challenging task. To meet this challenge we have to be familiar with the technologies and system architectures on the CDMA digital cellular system. The demand for high speed mobile wireless communications is rapidly growing. DS-CDMA plays the best competitive role for achieving the high data capacity and spectral efficiency requirements for communication systems. This paper represents the performance analysis of CDMA using direct sequence and frequency hopping technique in a Fading & AWGN Channel. It also concerned with how well DSCDMA performs when transmitted over an Additive White Gaussian Noise (AWGN) channel and/or both AWGN and the fading channels. In order to investigate this, a simulation model created and implemented using MATLAB. The Modulated signal transmitted over the fading, AWGN, and/or both channels for various signal-to-noise ratio (SNR) values. To evaluate the performance, for each SNR level, the received signal demodulated and the received data compared to the original information. The result of the simulation is shown in a plot of the bit error rate (BER)/error probability versus SNR, which provides the information about the systems performance.
