PERFORMANCE ANALYSIS OF MCCDMA SYSTEM IN RAYLEIGH CHANNEL USING QPSK MODULATION
Journal Title: Indian Journal of Computer Science and Engineering - Year 2015, Vol 6, Issue 1
Abstract
In this paper, the error performance of an MC-CDMA system is analysed with the help of Quadrature Phase shift Keying (QPSK) as the modulation technique mixed up with Additive White Gaussian Noise (AWGN) in the Rayleigh channel. CDMA suffers with the problem of selective frequency diversity during the downlink process. Orthogonal Frequency Division Multiple Access (OFDMA) techniques combine with the CDMA technique which arises to a Multi Carrier CDMA. As the number of users are increased the QPSK system performance better. This performance analysis is done with the calculation of the Bit Error Rate (BER) for the MC-CDMA system. The simulation is done using Matlab software.
