In the previous chapters we examined some of the implications of the MIMO capacity formula. As we have seen, the statistics of the MIMO capacity are dependent on the statistics of the channel matrix and the average signal-to-noise ratio at the receiver, which we denote by ρ. Both the statistics of H and the value of ρ depend on the propagation characteristics of the channel; thus, an understanding of propagation is important in order to predict and understand the performance of MIMO communication systems. Because MIMO techniques are designed to operate in a scattering environment, we focus on channel phenomena that give rise ...
