On the performance of 4G mobile wireless systems with multiple antennas

This paper studies physical layer performance of LTE and WiMAX schemes used in fourth generation (4G) wireless communication systems when multiple antennas are employed in the receiver to provide diversity. Bit Error Rate (BER) plots obtained from simulations are presented to evaluate system performance with and without diversity and to do a side-by-side comparison of the two main 4G wireless technologies.
