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.
