摘要: 提出了一种基于三阶循环统计量的波束成形方法。并将该波束成形方法与空时分组编码联合应用,提出了一种基站采用双天线阵列发射,移动终端多天线阵元接收的波束成形与空时分组编码联合处理新方案。本方案对移动终端的接收性能以及整个无线通信系统的容量都具有良好的改善作用。计算机仿真结果也证明了本方案的有效性和优越性。

关键词: 循环统计量, 波束成形, 空时分组编码

Abstract: A beamforming approach based on third order cyclic statistics is presented in this paper.And a new beam space time block coding scheme with this approach by using dual antenna arrays at base station and multi antenna elements at mobile terminal is proposed.This scheme can improve mobile terminal receiving performance and increase the communication capacity for entire wireless communication system.Simulation results show the effectiveness of this scheme.

Key words: beamforming, cyclic statistics, space-time block coding
