Performance Analysis of MIMO-OFDM (802.11n System) for WLAN Channel Model

For wireless communication system multipath fading is a common problem specially in city areas where a large number of buildings reflects the radio signals which results in interference amongst the reflected signals which causes the multipath fading effect since its selective by nature some spectrum at some specific location cancels out hence the receive signal losses some part of their information this abruptly increases the BER of communication system in slight movement of receiver, this paper specially analyzes the BER performance under Rayleigh fading channel conditions of MIMO-OFDM in presence of AWGN for different number of subcarrier, different number of users, and different path gains system analysis is performed by simulating the MIMO-OFDM using MATLAB program, and finally the paper also presents a comparison between simulated results.
