| Abstract: | Spatial subchannels in multiuser Multiple Input Multiple Output/Orthogonal Frequency Division Multiplexing(MIMO/OFDM) systems are investigated.A wireless resource scheduling is proposed to make the throughput maximize while rate request is satisfied.The simulation results show that the proposed algorithm achieves better performance than beam-forming.The capacity is improved through using spatial subchannel efficiently,and the fairness of users is also effectively protected. |
