发送端联合预处理方法、装置及系统制造方法及图纸

本发明专利技术实施例涉及发送端联合预处理方法及装置，该方法包括：获取第一阶段的至少一个接收端设备到至少一个发送端设备方向的第一信道矩阵和至少一个发送端设备到至少一个接收端设备方向的第二信道矩阵；根据第一信道矩阵和第二信道矩阵，应用信道对称性确定第一信道矩阵和第二信道矩阵之间的校正对角参数；获取第二阶段的至少一个接收端设备到至少一个发送端设备方向的第三信道矩阵，其中，第一阶段在第二阶段之前；在第二阶段基于第三信道矩阵、校正对角参数，对至少一个发送端设备待发出的信号进行发送端联合预处理。由上可见，本发明专利技术实施例中，对干扰进行抵消的效果好。

Transmitter Joint Preprocessing Method, Device and System

The embodiment of the present invention relates to a joint pre-processing method and device at the transmitter, which includes acquiring a first channel matrix in the direction of at least one receiving device to at least one transmitting device in the first stage and a second channel matrix in the direction of at least one transmitting device to at least one receiving device in the first stage, and applying channel symmetry according to the first channel matrix and the second channel matrix. Determine the corrected diagonal parameters between the first channel matrix and the second channel matrix; obtain the third channel matrix from at least one receiver device to at least one sender device in the second stage, where the first stage precedes the second stage; and transmit the signal to be emitted by at least one sender device based on the third channel matrix and corrected diagonal parameters in the second stage. Combined pretreatment at the sending end. It can be seen from the above that the interference cancellation effect is good in the embodiment of the present invention.
