Capacity of antenna arrays with space, polarization and pattern diversity

We present an analytical characterization of the multi-antenna capacity in the limit of a large number of antennas. In contrast with previous studies, the entries of the channel matrix are not restricted to be identically distributed thus incorporating diversity mechanisms that are otherwise excluded, such as those based on the use of antennas with distinct polarizations and radiation patterns. In addition to the capacity, first-order expressions in the low- and high-power regimes are also evaluated both asymptotically and non-asymptotically.
