Joint interference cancellation and subtraction for a hybrid receiver in kronecker correlated MIMO wireless channels

Abstract

Several works have evaluated the performance of MIMO transmission structures using the uncorrelated fading assumption. This idealized consideration may not be true in a typical downlink outdoor wireless system. In this type of scenario higher fading correlations are present at the transmitter due to the height of the base-station relative to the ground. In this work we present a Hybrid MIMO receiver for combined spatial multiplexing - transmit diversity and evaluate its performance when fading correlation is present at the transmitter. MIMO fading correlation is simulated according to a recently proposed Kronecker model and our results show the performance behavior of our hybrid receiver due to correlation.
