摘要
为多用户A lamouti空时分组码(STBC)系统提出了一种自适应波束形成方案,此方案基于最小均方差(MMSE)准则。因为使用了自适应波束形成方法的原因,不需要得到用于相干解码的信道状态信息。仿真结果表明,在多用户系统中这种方案有很好的性能,一个有N个接收天线的此种方案能支持N个用户。
A reception scheme using adaptive beamforming for muhiuser Alamouti - type space - time block code is proposed. This scheme performs space - time processing to optimally estimate the transmitted space - time block coded symbols based on the minimum mean square error (MMSE) criterion. Simulation results show that this scheme achieves good performance in a multiuser system. With N receiving antennas the scheme can support N users each with two antennas.
