Energy Efficiency of Massive-MIMO Heterogeneous Network

Abstract

Massivemassive multiple-input multiple-output (MIMO) and heterogeneous networks are two Potential technologies in the 5G. The application of Massive-MIMO to heterogeneous network can effectively eliminate the interference and improve energy efficiency.In this paper, the network is optimized by using JointSpatial Division and Multiplexing (JSDM) and zero forcing algorithm, analyzing the spectrum efficiency and energy efficiency of the heterogeneous network.The relationship between the energy efficiency and the number of antennas and the transmission power of the base station are considered by simulation.
