Performance Analysis of MIMO OFDM System for Wireless Communications

Abstract

quotOrthogonal frequency division multiplexing (OFDM) technology newlinehas been developed into a popular scheme for wideband digital newlinecommunications since it is an efficient and effective technique to deal newlinewith frequency selective fading as well as achieving high speed data newlinetransmissions. In the recent years, multiple-input multiple-out (MIMO) newlinetechnology has attracted lots of attention because it significantly newlineincreases the data throughput (multiplexing gain) and link reliability newline(diversity gain) without additional bandwidth or transmission power. newlineThe combination of the MIMO and OFDM, i.e. MIMO-OFDM system, newlinehas been widely recognized as the next generation broadband wireless newlinesystem. In particular, this thesis is concerned with the effectiveness of newlineOFDM as a modulation technique for wireless communications, Intercarrier newlineInterference reduction, Peak to average power reduction of newlineOFDM, Equalization techniques for multiple Input Multiple output newline(MIMO-OFDM) system, Channel capacity estimation and mobile speed newlineestimation over flat fading channels.quot newline newline
