Abstract :
In this paper, we analyze the performance of multicarrier spread spectrum systems in a multipath Rayleigh fading channel using frequency domain equalizer. Pilot-based channel estimation is done to compensate for the amplitude and phase distortions of the signal in the channel. BER performance is found for both AWGN and fading channels. It is found that the performance degrades as the number of active users increases due to increase in MAI
