Simulation and analysis of MIMO-OFDM for a 4G cellular network

Abstract

In the disciplines that study communications, there have been increasing interest in ways and means to improve the technology behind the mobile phone. This interest extends from the antennas used to broadcast the signals to the modulation techniques used on the signals themselves. The theory is that the antennas can be improved by applying a technique known as MIMO, or multiple-input multiple-output, and the signals can be improved by the modulation technique of OFDM, or orthogonal frequency divisional multiplexing. This concept, as a whole, is known as MIMO-OFDM, and will hopefully be used as the basis of the 4G cellular network in coming years. In developing these, however, it also means covering a wide of topics such as signal interference, channel capacity, fading, et cetera. The aim of this thesis is to analyze this MIMO-OFDM concept, and all it entails, to determine if it is indeed possible to be used as the basis of a cellular network. This will be by means of a computer simulation in C/C++
