Abstract :
In this paper we present a sub-carrier and power allocation algorithm for multiuser MIMO-OFDM system. In order to minimize the total transmit power under the condition that users´ QoS requirements are satisfied, the proposed algorithm assigns the sub-carrier to user that has the maximum gain on all spatial sub-channels on each sub-carrier. Simulation results show that the proposed algorithm converges more rapidly than previous algorithms.
