| 摘 要： | 为减少多基站协作波束成形系统中基站间的信息交换量和用户信道信息反馈量,提出一种基站联合利用有限反馈信道参数和信道空间相关矩阵估计信道矢量函数的方法;基于所估计的信道矢量函数,提出一种多基站协作扩展迫零波束成形算法。相比已有的多基站协作波束成形方案,所提算法能在反馈/回程开销和系统性能之间取得更合理的折中,计算仿真验证了所提算法的有效性。

| Abstract: | In order to reduce the amount of information exchange between base stations(BS) and user feedback information required by multicell cooperative beamforming systems,an estimation algorithm of channel vector function was proposed by making jointly use of limited feedback channel parameters and channel spatial correlation matrix.Based on the estimated channel vector functions,a multicell cooperative extended zero-forcing beamforming algorithm was developed.Compared with the existing multicell cooperative algor... |
