Abstract
The emergence of WIMAX has attracted interest from wireless communication researchers. This paper discusses the OFDM for wireless communication. It include Bit Error Rate and Symbol Error Rate versus the ratio of bit energy to noise power spectral density (Eb/No) for different communication channels like AWGN channel, Rayleigh multipath channel, combined Rayleigh multipath with AWGN channel and Rician channel. The simulation is designed on computer MATLAB 9 version with 64-point FFT. It demonstrates that AWGN has better performance than any other channel. The BER of AWGN channel is 10-5 at 8dB SNR for Rayleigh multipath channel is 10-4.5 at 40dB SNR for Rayleigh multipath channel with AWGN is 10-4 at 30dB SNR and for Rician channel is 10-3 at 30dB SNR. The SER of AWGN channel is 0.02 at 12dB and approximately 0 at 14dB whereas SER for Rayleigh multipath channel with AWGN is 0.0009 at 30dB. So, AWGN channel has better SNR than any other channel. It can be used for OFDM Bluetooth 802.11g-2003, fixed WIMAX 802.16-2004 and mobile WIMAX 802.16e-2005
