Performance Evalution of WiMAxx OFDM System Over Multi Path Fading Channel
WiMAX is a wireless technology which offers high data rate transmission in broadband. In this paper, the architecture of the WiMAX physical layer simulator is presented. The main blocks are implemented with the aid of the Matlab and the Bit Error Rate (BER) curves are presented in this paper is: the BER versus the ratio of bit Energy to Noise power spectral density (Eb/No). The system parameters used in this paper are based on IEEE 802.16 standards. The simulation model built for this research paper, demonstrates that Doppler shift 10 and QPSK modulation has better performance than other value Doppler shift and 8PSK modulation over the Rayleigh and Rician fading channels.
