Abstract

In this paper, the performance analysis of massive multiple input multiple output (MIMO) multiuser transmit beamforming techniques is studied using a generalized spatial channel model. In particular, heuristic beamforming techniques (such as maximum ratio transmission beamforming technique, zero forcing beamforming technique and regularized zero forcing beamforming technique) as well as optimal beamforming technique are considered. A generalized spatial channel model is used for more practical results in mobile communication system. The spectral efficiency is used in the analysis to describe the performance. Special attention is given to the effect of massive MIMO technique on the performance of different considered beamforming techniques. The numerical results show that with a relatively small number of antennas there is a need for optimal beamforming to achieve higher spectral efficiency. It is also shown that the performance of heuristic beamforming techniques approaches the performance of optimal beamforming techniques when the number of transmitting antennas is highly increased.
