Abstract

We analyze the capacity of multiple-input-multiple-output (MIMO) systems in microcellular environments, taking into account the frequency selectivity of the wireless channels. We use a new data evaluation method that allows to evaluate the probability density function (PDF) of the capacity from a single measurement. We find that the frequency selectivity of the channel makes the PDF more peaked, and thus increases the outage capacity compared to the frequency-flat case. However, capacities are considerably lower than predicted for ideally decorrelated channels
