Performance Analysis of MIMO-OFDM Wireless Communication System through Channel Estimation (original) (raw)

2017

Abstract

Future wireless communication system have to be designed to integrate features such as high data rates, high quality of service and multimedia in the existing communication frame work. Increased demand in wireless communication system has led to demand for higher network capacity and performance. Higher bandwidth, optimized modulation offer practically limited potential to increase the spectral efficiency. Hence MIMO systems utilizes space multiplex by using array of antenna’s for enhancing the efficiency at particular utilized bandwidth.OFDM-based air interface, spatial channel modelling, transceiver design, channel estimation and minimizing the BER ratio by modifying the Maximum Likelihood function through channel estimation.
