Channel Models for MIMO Systems in 4G Networks

Abstract

This project attempts to study the behavior of bad urban and rural macro-cells channel models for (4x2) and (2x2) MIMO multipath fading channel. The channel behavior is investigated for (8x2) MIMO system under indoor propagation environment as well. The fading envelops for the multipath components are observed and analyzed manipulating different parameters; changing the symbol rate, doppler shift, and antennas spacing in order to understand the behavior of the MIMO channel so as to ease the deployment of the entire MIMO system. The simulation results shows that the channel behavior is getting better and becomes more stable when increasing the symbol rate and antennas spacing, and at the same time reducing the Doppler shift. The operation frequency’s influence on the path-loss that the propagating signals suffer is investigated.
