Analysis of Beam Division Multiple Access in Massive MIMO Communication Systems

The main objectives in wireless communication, mostly after the 4G systems introduction are increased channel capacity, improve data rate, decrease in latency and better quality of services. Hence drastic improvements need to be made in architecture of the cellular network to meet up these demands.This paper presents the information of massive Multiple Input Multiple Output (MIMO) system that consists of hundreds of antenna elements. With advanced access technology namely Beam Division Multiple Access (BDMA), the Base station (BS) serves as multiple users. The BDMA technique serves multiple users simultaneously by focusing parts of an antenna beam towards the position of the mobile user devices thereby giving multiple accesses to mobile users and hence increasing the capacity of the system significantly. The antenna beams can be steered to desired direction depending on traffic environment and nulls are placed in undesired direction. Thus the problem created by intended jammers are considerably reduced.
