Performance Analysis of Transmit Diversity and Spatial Multiplexing MIMO Techniques in LTE Cell Edge Coverage Areas

As Mobile data usage is becoming more and more in radio communications systems, Techniques are needed to enhance Mobile network performance and overcome problems like low-SNR at cell edges. MIMO wireless technology is one of these techniques. In LTE and LTE-A, MIMO is able to considerably enhance network performance and overcome cell edge problems by increasing the number of receive and transmit antennas. With every pair of antennas added to the system, More network performance enhancement can be achieved. This makes MIMO wireless technology one of the most important wireless techniques to be employed in 4G and 5G mobile networks in recent years. In this paper, a performance analysis of Transmit Diversity and Spatial Multiplexing MIMO techniques will be introduced studying its effect on Downlink throughput enhancement in LTE networks cell edge coverage areas.
