In this work, we study the performance of multiple-input multiple-output (MIMO) wireless systems. Specifically, we examine their capacity fordifferent system scenaria and with different propagation models. The MIMO systems analyzed include the single-user case where multipleantennas are used and the multiuser case with two users present and a single antenna at each of them and the base station. We examine the capacity properties in the case of unknown and known propagation channel. In the case where the latter is infeasible, we present ways to estimate the optimal power allocation and approach the system capacity.To simulate communication systems under various propagation environments, we use Neben's MIMObit which offers an integrated platformthat fully takes into account the antennas used at the transmitter and the receiver. We evaluate the accuracy of simulation results provided by MIMObit using dipole antennas created in its graphical user interface and in CST Microwave Studio. Finally, we make some capacity estimation comparisons using the channels produced by MIMObit and Matlab.​
