ABSTRACT

This chapter discusses various performance metrics of Multiple-input multiple-output systems with spatial multiplexing over various generalized fading channels. It shows some insights to analytical expressions of these metrics and simulation results using MATLAB. The diversity gain is achieved as a result of multiple antennas at the receiver when multiplexing is used for transmission. Spatial multiplexing is seen as a potential technology for improving transmission rates. Parallel transmission from multiple antennas requires separate radio frequency chain for each antenna at transmitter. Detection complexity is directly related to the computational power required at the receiver and battery life of mobile equipment. The detection complexity varies linearly with the number of receiver antennas. It varies exponentially with the number of transmitter antennas and modulation order. In spatially multiplexed MIMO systems, the transmitted symbol is a vector of signals coming from constellation of digitally modulated signals.
