Performance Analysis of HOM in LTE Small Cell

Abstract

This paper deals with the performance analysis of HOM (higher order modulation) in LTE-A system. Firstly, we analyzed the requirement of HOM in small cell deployment, and then we analyzed the problem of EVM (Error Vector Magnitude) modeling in LTE system. With the assumption of small cell deployment, some link level simulation results are proposed, where the impacts of EVM on different MCS (modulation coding style) are compared. The simulation results show that the performance of HOM in small cell is very sensitive to EVM. In this paper, the other factors which would impact the performance of HOM are also mentioned.
