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

摘要

Fading is a common problem for the wireless communication system especially in urban areas where a large number of buildings reflecting the radio signals that result in interference between the reflected signals makes the fading effect since multiple selective nature of the spectrum at some specific place cancels out so the reception signal loss any part of your information in this sharply increases the communication system BER in slight motion of receiver, this paper specially analyzes the BER performance under Rayleigh fading channel conditions of MIMO-OFDM in presence of AWGN (Additive White Gaussian Noise) for different number of Transimitting, 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
