A Coordinate Multiple Points Scheme Based on SLNR Criterion with Least Square Channel Estimation

Chapter
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 127)

Abstract

In this paper, we consider the problem of co-channel interference mitigation in a TD-LTE coordinated multiple points (CoMP) system where the linear pre-coding matrix is jointly optimized across a set of coordinated sites. The objective function to be maximized is the signal to leakage and noise ratio (SLNR) of all users subject to a pooled power constraint where the channel status information (CSI) is acquired through ideal or a linear interpolation channel estimation method, respectively. We will focus on the downlink scenario where each user is equipped with one antenna. Simulation results of the perfect and estimated CSI are provided for comparison.
