    • The deformation correlation matrix or a correlation matrix of each channel coefficient matrix from multiple reception nodes which shares a wireless resource, or correlation matrix of an interference channel coefficient matrix feeds back to a transmission node. And the transmission node decides a pre-coder based on a value which minimizes a value decided by the set of the correlation matrix of the interference channel matrix or a value which maximizes a value decided by the correlation matrix or the deformation correlation matrix of the channel coefficient matrix, respectively, and pre-codes a transmission signal by using the decided pre-coder.
    • 共享无线资源的多个接收节点或干扰信道系数矩阵的相关矩阵的每个信道系数矩阵的变形相关矩阵或相关矩阵反馈给传输节点。 并且传输节点基于使由干扰信道矩阵的相关矩阵的集合决定的值最小化的值来确定预编码器,或者使由相关矩阵或通道的变形相关矩阵确定的值最大化的值 系数矩阵,并通过使用决定的预编码器对传输信号进行预编码。
