STUDIES ON MIMO OFDM SYSTEM AND IT’S TIME DOMAIN SIGNAL DETECTION

Abstract

Multiple-input multiple-output (MIMO) wireless technology in combination with orthogonal frequency division multiplexing (MIMO OFDM) is an attractive air-interface solution for next-generation wireless local area networks (WLANs), wireless metropolitan area networks (WMANs), and fourth-generation mobile cellular wireless systems. This thesis provides an overview of the basics of MIMO-OFDM technology and focuses on a new system model in which the received OFDM block is left shifted by J samples to improve the system performance and an equalizer to cancel most of the intersymbol interference .It is shown by simulation that the channel lengths have insignificant effect on the proposed algorithm.
