Abstract
We develop a semi-deterministic semi-stochastic channel model for the multiple-input multiple-output (MIMO) system under the macrocell environment with local-to-mobile and local-to-base scatterers, and show that the channel capacity, multiplexing and diversity gains are multipath limited in the sense that they are limited by the number of multipaths around the base station. We derive a lower bound on the ergodic capacity and an upper bound on the average pairwise error detection probability. It is shown that the base-station array affects the two different information theoretic measures through the same metric, and the fading correlation matrix also appears in the two bounds with the same form. Numerical examples show the tightness of the two bounds.
