摘要 机会波束技术通过形成随机波束达到了与信道奇异值分解相同的吞吐量,不需要准确地信道状态信息,反馈量少。在正交波束提供的复用增益与各波束间的干扰间折衷而需要最优的发射波束数,为了获得不同情况下的最优波数个数,该文采用数值分析的方法,分析了多用户多输入单输出机会波束系统中选择不同发射波束个数时的容量,通过比较不同波束个数时系统的容量,得到最优发射波束个数。结果表明,最佳波束的个数随用户数增加而加大,随平均信噪比增加而下降。 The opportunistic beamforming system can achieve the same throughput with channel singular value decomposition,and doesn＇t need perfect channel-state information.Opportunistic multi-beamforming improve system throughput by transmitting orthogonal beam,when increasing transmit beam number,the space-reuse gain will improve and the interference between beams will increase,which is contradict.To obtain the optimum number of transmitting beams,the paper analyze the throughput of MISO opportunistic beamforming system＇s capacity when adopt different number of transmitting beams.The results show that the optimum transmitting beam number is increased with users number,decreased with the average SNR.
