Performance of MUTP-Aided MIMO Systems Over Correlated Frequency-Selective Wireless Communication Channels: A Multi-Cell Perspective

Free registration required

Executive Summary

In this paper, the authors investigate the performance of MultiUser Transmitter Preprocessing (MUTP)-aided Multiple-Input Multiple-Output (MIMO) systems in a multi-cell multiuser setting for both UpLink (UL) and DownLink (DL) transmissions, where Co-Channel Interference (CCI) is the major channel impairment. CCI can considerably reduce data rates resulting in outages in cellular systems, particularly at the cell edges in DL transmission. The MUTP considered in this paper is based on Singular Value Decomposition (SVD), which exploits the Channel State Information (CSI) of all the users at the Base Stations (BSs), with the aid of BS cooperation, and only individual users' CSI at the Mobile Stations (MSs) for both UL and DL transmissions.
