Abstract

The paper proposes an efficient way to simulate MIMO-OFDM systems with computational electromagnetics. The key idea is to extrapolate channel responses at various frequencies based on the simulated electric field values at a certain frequency. Then it is shown how to fit the simulated and extrapolated channel responses into a statistical channel model. The system capacity under a MIMO-OFDM ad-hoc system scenario is analyzed and it can be seen that both spatial and frequency diversity have been achieved.
