Abstract

This paper developed a model of a WiMAX system using simulation in Matrix laboratory language (MATLAB) for finding the impact of cyclic prefix on which BER calculations is carried out. The WiMAX signal was transmitted over the AWGN channel various signal-to-noise ratio (SNR) values. To evaluate the performance, for each SNR level, the received signal was demodulated and the received data was compared to the original information. The result of the simulation is shown in the plot of the bit error rate versus Eb /No, which provides information about the system’s performance. The convolution coding and interleaving is applied to improve BER performance of WiMAX system for various digital modulation schemes like BPSK, QPSK, and QAM.
