Investigation of Effect of Communication Bandwidth and Length of Coherence Block on Energy Efficiency and Area Throughput in Massive Multiple-Input and Multiple-Output Systems

The popularity of wireless communication is increasing day by day. This has led to the fact that data transfers via GSM have reached very high levels. Data transfers via GSM, which are continuously growing, increase the density of data traffic, thus necessitating high level of area throughput performance in the near future. One of the most effective ways to increase area throughput is seen as increasing spectral efficiency (SE). Very high amount of energy required to increase the spectral efficiency. High energy consumption is costly and harmful to the environment so thus makes it necessary to increase the energy efficiency (EE). Massive multiple-input and multiple-output (Massive MIMO) systems are one of the techniques that can be used to increase the both of area throughput and energy efficiency. In this study, length of coherence block – communication bandwidth combinations are investigated by using Massive MIMO systems in cases which there are various numbers of users and active antennas. As a result of the studies, the effects of length of coherence block and communication bandwidth on EE - area throughput tradeoffs were evaluated.
