Abstract
Radio resource allocation algorithm is proposed for multiuser MIMO-OFDM environment providing proportional fairness. Familiar MIMO radio channel model is extended for OFDMA transmission, exploiting multiuser diversity. Antenna selection is realized for maximizing overall data rate based on MIMO channel estimation. Adaptive M-QAM modulation is performed on selected antennas on each subcarrier, taking into account singular value decomposition based power gain values from the analytical calculation of MIMO channel capacity. Transmit power control is included over subcarriers and transmit antennas providing fairness among users.
