Power, Linearity, and Efficiency Prediction for MIMO Arrays

Since MIMO array elements are electromagnetically coupled, the waves fed to the antennas also drive the power amplifier (PA) output ports, creating an apparent variable load at each PA output. Simulation is a powerful tool in understanding how these MIMO systems behave. Such simulators should be able to reproduce the main figures of merit of the transmitter, namely, output power, distortion, and efficiency.
