Abstract :
Optimum signaling is studied for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems with multiple links which mutually interfere. Numerical results show that using the optimum approach for cases without interference does not always achieve system capacity. In some cases, the overall system performance is improved by forcing users to use different subcarriers or to transmit using less antennas or both.
