MIMO-OFDM是未来宽带无线通信接口的有效架构.本文提出了一种基于多用户MIMO-OFDM系统的空间子信道分配算法,以获取最大的系统吞吐量为目标,推导了子载波分配准则,给出了相应的算法流程;为了减小计算量,本文进一步提出了基于时频块的简化设计.仿真结果表明,该算法具有良好的性能,有效地提高了系统的传输速率.
英文摘要：
MIMO/OFDM is an effective architecture for future wireless communication systems. A spatial subehannel allocation algorithm based on multiuser MIMO/OFDM systems is proposed in this paper. With the goal of maximizing overall data throughput we derive the criteria of subearrier allocation and develop the adaptive allocation approach,furthermore ,a bloekwise loading design which may decrease the computational load is suggested. The simulation results show that our proposed algorithm can achieve good performance and high total transmission rate efficiently.
