PERFORMANCES STUDIES OF BEAMFORMING TECHNIQUES IN A MASSIVE MIMO SYSTEM

Telecommunication Engineering

Massive MIMO technology could become a revolutionary technology in wireless communications, increasing cellular capacity and efficiency in high-traffic urban areas. For example, the diversity introduced by multipath propagation is exploited to allow the transfer of data between a base station and several users in the same time and frequency resource. The use of millimeter waves allows us to implant more antenna in a system with reduced forms. The use of the beamforming technique optimizes Massive MIMO technology. Three beamforming approaches for receiving signals in the presence of interference, with knowledge of the direction of arrival, have been developed. The phase shift technique is less efficient than the other two. On the other hand, the efficiency of the two other techniques depends on the estimation of the signal’s direction of arrival.
