BER ANALYSIS OF WIMAX IN MULTIPATH FADING CHANNELS

Navgeet Singh, Amita Soni

Abstract: In this paper, an effort has been made to inspect the performance of WiMAX OFDM physical layer under the effect of noise. An End-to-end baseband WiMAX OFDM physical layer has been modelled in Multipath fading environment using MATLAB Simulink. BER has been evaluated for the Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), 16 Quadrature Amplitude Modulation (16 QAM) and 64 Quadrature Amplitude Modulation (64 QAM) schemes over a range of SNR (dB). The BER of a digital communication system is an important figure of merit for quantifying the integrity of data transmitted through the communication system. Several plots between BER and SNR (dB) for the abovementioned modulation schemes in Rayleigh and Rician fading channels have been investigated for the analysis.

Keywords: BER (Bit Error Rate), SNR (dB), Multipath Rician Channel, Multipath Rayleigh Channel, WiMAX, BPSK, QPSK, 16 QAM, 64 QAM.
