摘要 本文根据相关值序列只与相邻的两个比特符号有关而且具有确定性的特点 ,提出了利用相关值序列来得到波束形成权的盲波束形成方法 .该方法既考虑了对干扰的最大抑制 ,又强调了对多径信号的充分利用 .它利用了期望用户信号的所有能量 ,不需要已知信道参数 ,也不需要发训练序列 .另外 ,提出的方法还具有不受非零时延的相关值大小的限制。 Based on correlative sequence determined by two neighbouring symbols,a new method of blind beamforming is proposed in this paper.Mitigating interference and making full use of the multipath signals,the new method utilizes the total energy of the desired user and does not require the channel parameters and training sequence.It is not restricted by the correlative value corresponding to nonzero time lag.It is characterized by identifying the multipath signals of the desired user and requiring less symbols for beamforming.
