Energy Efficiency in Multicell Massive MIMO network using Zero Forcing technique

Abstract

Wireless system characterized by multipath fading can be disregarded by Massive multiple input multiple output (MIMO) a promising candidate for enhancing energy efficiency in wireless network. The energy efficiency can be realized by zero forcing (ZF) linear processing scheme for fixed power consumption in the massive MIMO network. The channel is estimated in imperfect channel state information (CSI) with K user equipment and M base station in a symmetric multicell scenario with different reuse pattern across cells. The simulation results prove that ZF inheritance performs optimally and it is compared to that of conventional ZF system.
