Study and imulation of the MIMO enabling technology in the LTE system

Abstract

Multi-antenna (MIMO) techniques are reported to improve the performance of radio communication systems in terms of their capacity and spectral efficiency. Long Term Evolution(LTE), one of the candidates for fourth generation(4G) mobile communication systems has MIMO as one of its underlying technologies and ITU defined channel models for its propagating environment. This project undertakes a comprehensive verification of the performance of spatial multiplexing MIMO in the downlink sector of LTE. The study and the analysis is done by the use of models built using MATLAB and Simulink to carry out simulations. It is deduced that spatial multiplexing improves spectral efficiency and increases data rate of the transmission. This is more pronounced if more antennas are used in the transmitter and the receiver. Furthermore, precoding operation for open loop and closed loop spatial multiplexing depends on the channel conditions.
