Performance Analysis of the Combined AMCMultiuser MIMO LTE-Advanced System

Abstract

The growth of wireless networks in recent years coupled with applications demanding high data rates. This paper considers feedback and pre-coding design for multi-user MIMO in LTE-Advanced systems. LTE aims to provide improved service quality over 3G systems in terms of throughput, spectral efficiency, latency, and peak data rate, and the MIMO technique is one of the key enablers of the LTE system for achieving these diverse goals. In this paper, we propose a AMC based pre-coding for multiuser multiinput multi-output (MIMO) systems. Adaptive modulation and coding (AMC) is a powerful technique to enhance the link performance by adjusting the transmission power, channel coding rates and modulation levels according to channel state information.
