ABSTRACT
This chapter presents exact results on the performance of wireless communications systems employing multiple antennas at both the transmitter and receiver (known also as multiple-input multiple-output (MIMO) systems), in terms of the channel capacity, capacity complementary cumulative distribution function, outage probability, and average bit error rate. We study effects of various important factors, such as the co-channel interference (CCI), the line-of-sight path (Rician fading), fading correlations, and different levels of availability of channel state information (CSI) at the transmitter (perfect CSI, partial CSI, and no CSI). Numerical examples are also provided and discussed to illustrate the mathematical formalism and to show the impact of these factors.
