PERFORMANCE ANALYSIS OF BIT-ERROR RATE (BER) OF THE MC DS-CDMA UNDER AWGN & RAYLEIGH FADING CHANNELS

Multi-Carrier Code Division Multiple Access (MC- CDMA) is a multiple access scheme used in OFDM- based systems, allowing the system to support multiple users at the same time. Multi Carrier modulation has a significant role in mobile communication because of frequency diversity and bandwidth efficiency. Multi-Carrier Code Division Multiple Access (MC-CDMA) suffers from timing errors due to the large number of carriers. So in this paper  we  present  the  Analysis of  Bit-Error  Rate (BER) of the MC DS-CDMA System under Additive white Gaussian noise (AWGN) and multipath rayleigh fading channel.
