Information Theoretic Comparison of MIMO Wireless Communication Receivers in the Presence of Interference
Abstract
Multiple-input multiple-output (MI MO) wireless communication provides a number of advantages over traditional single-input single-output (SISO) approaches including increased data rates for a given total transmit power and improved robustness to interference. Many of these advantages depend strongly upon the details of the receiver implementation. For practical communication systems a competition between communication performance and computational complexity exists. To reduce computation complexity suboptimal receivers are commonly employed. In this paper the details of a variety of receivers are incorporated into the effects of the channel so that information-theoretic performance bounds can be exploited to evaluate receiver approaches. The performance of these receivers is investigated for a range of environments. Two classes of environments are considered: first channel complexity characterized by the shape of the narrowband channel-matrix singular-value distribution and second external interference Receiver approaches include minimum-mean-squared error minimum interference and multichannel multiuser detection (MCMUD) given various assumed limitations on channel and interference estimation Receiver performance implications are also demonstrated using experimental data.
