摘要 为保证多播服务质量(QoS)要求,建议一种所有组成员满足信号与干扰加噪声比(SINR)门限的功率约束下多输入多输出-正交频分复用(MIMO-OFDM)波束成形优化模型,提出在最大化多播MIMO分集策略下接收波成形算法,并得到发射波成形和接收波成形矢量及满足QoS要求所需最小发射功率。通过仿真与性能分析,证明满足最小SINR要求的波成形优化方法不仅能得到最小发射功率,同时具有改善多播用户间公平性的特性,并得到一些重要结论。 In order to guarantee multicast quality of service（QoS）,a beamforming optimization model for multiple-input multiple-output orthogonal frequency division multiplexing（MIMO-OFDM） is proposed.In the model,signal to interference plus noise ratio（SINR） of all members in a multicast group is above the threshold.Then the maximum MIMO diversity strategy and the corresponding optimized receiving beamforming algorithm are suggested.Finally,the solutions of transmitting and receiving beamforming vectors are obtained by software define radio（SDR） algorithm,and the minimal transmitting power can be obtained while the SINR for QoS is guaranteed.The simulation results and the performance analysis show that in the multicast beamforming optimization manner for guaranteed SINR,not only the minimum transmitting power can be obtained,but also the fairness performance among members in a multicast group is improved,and some other important conclusions are deduced.
