摘　　要：提出一种不需要额外的用户到协作小区的信道信息反馈的干扰消除方法.通过研究单用户多输入多输出协同多点传输(CoMP-SU-MIMO)系统中用户接收信号经过接收算法处理后所受到的干扰情况和双极化信道的特性,结合现有反馈技术,提出了一种新的干扰消除方法.利用双极化信道特征矢量的正交特性,达到较好的干扰消除效果,减少了算法复杂度.A novel interference cancellation algorithm without requiring extra channel information,namely the information between user equipment and cooperated cells is proposed.By investigating the interference processed at the receiver in coordinated multi-point transmission single user multiple-input multiple-output（CoMP-SU-MIMO） transmission and the characteristics of dual polarized channel,combined with the existing limited feedback technologies,a novel interference cancellation algorithm was proposed.Utilizing the eigenvector＇s orthogonality of polarized channel,the proposed algorithm could achieve better performance on interference cancellation,and the algorithm complexity can be reduced as well.
