【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。更多还原

【Abstract】 A reception scheme using adaptive beamforming for multiuser 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.更多还原
