Abstract :
This paper presents the performances BPSK / OFDM systems in terms of Bit Error Rate (BER) as a function of Signal to Noise Ratio (SNR) using different types and lengths of Guard Interval. The simulations were carried out over AWGN and Rayleigh fading channels, and the results have been compared with the theoretical ones. Based on those results, a number of conclusions have been highlighted in the last chapter of the paper.
