Multiple-input multiple-output (MIMO) antennas can be combined with orthogonal frequency division multiplexing (OFDM) to increase system throughput by spatial multiplexing. That is the requirement of high speed future wireless networks such as WLANs and WMANs. This paper investigates the radio resource management problem of MIMO-OFDM based wireless network systems in order to maximize the total system throughput subject to the total power and proportional rate constraints of each user. A low-complexity algorithm that separates subcarrier allocation and power allocation is proposed. Simulation results show that the proposed resource allocation algorithm can improve the throughput and also it can make the throughput be distributed more fairly among users than some other schemes.
