Performance Analysis Of MIMO-OFDM System

Abstract

Mobile communication is one of the important technologies in wireless communication. In Mobile communications face lot of many technical challenges. Fading, attenuation, channel Interference, Propagation path loss, multicarrier interference etc, occurs during the transmission of signals on a wireless channel. So need an efficient channel to transmit the signal without any distortions. High quality service has to be provided for the greater demand of capacity. Orthogonal frequency division multiplexing (OFDM) is a current and known technique for high efficient data transmission and high bandwidth data transmission; it can be achieved by converting the wideband signal into narrow band signals. In this paper, analyzed the performances of Bit Error Rate (BER) and spectral analyzes using Mat lab Software, and also predict the performance of Gaussian Noise channel (AWGN). It is suitable for long distance transmission without any distortions.
