Abstract
This paper presents the performances of BPSK, QPSK, 16QAM, 64QAM /Multi User Orthogonal Frequency division Multiple Access (MU-OFDMA) and Orthogonal frequency-division multiplexing (OFDM) systems performances in terms of Bit Error Rate (BER) as a function of Signal to Noise Ratio (SNR) using different lengths of Cycling Prefix. The simulations were carried out over AWGN and Rayleigh fading channels, and the results for the two systems have been compared. Based on those results, a number of conclusions have been highlighted in the last chapter of the paper.
