Abstract

The demand of attaining information and the wish to communicating anytime and anywhere has caused numerous innovations in the digital communication world. Today, approximately half of the people on earth somehow use wireless technology which is in every part of our lives. LTE (Long Term Evolution) and WIMAX (Worldwide Interoperability for Microwave Access) standards are the two leading wireless technologies, which support high data rates, multimedia applications, and voice video communications at very high speeds, also called 4G cellular systems in the global market.

These high expectations from wireless technology have revealed multiple antenna techniques which improve the performance and robustness of wireless channels using an array of antennas for both receiving and transmitting. Antenna arrays improve the channel quality by mitigating the effects due to multipath propagation.

In this thesis, better performance of LTE systems with multi antenna techniques is studied. After introducing multi antenna techniques, a wireless channel environment with fading paths is implemented using MATLAB software. The receive diversity techniques considered are maximal ratio combining (MRC) and selection combining (SC) and they are investigated for different number of antenna configurations. Also varying numbers of fading paths are simulated in the thesis. Finally, a comparison between LTE and WIMAX is performed for several fading paths and their performances are evaluated.
