Energy Efficiency in High Density Networks using Zero Forcing Technique

Abstract

The demand for high date rate in wireless network can be contented by the metric energy efficiency. It can be achieved by reducing the effect of fading which degrades the system performance by introducing interference in the network. Massive MIMO system is used to combat the effect of fading with the constraint of spectrum limitation. However, network performance gets limited due to increased number of users which introduces interference in the network. It can be compromised by precoding techniques like maximal ratio combining (MRC) and zero forcing(ZF) techniques. The work modeled in this paper is unified with zero forcing for analysis of energy efficiency and it is compared with exiting MRC technique. The attributes considered in performance analysis are energy efficiency and user equipment. Simulation results will prove that MRC is out performed by ZF in terms of maximized energy efficiency.
