Disclosed in the present invention is a transmission signal processing method and device, wherein the method comprises: using a pre-coding weight, pre-coding is performed for each user group of multiple user groups served by a base station and a pre-coded signal is obtained, wherein each user group includes a first class user and a second class user, and the signal to noise ratio of the first class user is greater than that of the second class user; the vector of the pre-coding weight of any user group belongs to a zero space of a channel gain coefficient matrix of the first class user in the other user group; the transmission signal is obtained by adding the pre-coded signal of multiple user groups. With the present invention, it solves the problem in the related technology that a low power signal of a strong user is interfered by a strong power signal of an adjacent weak user, and effectively avoids that the strong user receiving the low power signal is interfered by the high power signal on an adjacent beam, so that the performance of a MIMO-NOMA system is effectively improved. |
