A precoding method and matrix generation device for a coordinated multiple point (CoMP) multiple user MIMO (MU-MIMO) system, the method comprising the following steps: S1, a central control station acquires from each cell base station n (n=1,...,T) a base station transmission power Pn (n=1,...,T), the channel information Hn,i between the base station n and a user i, and a signal-to-noise ratio SNRn,i (i=1,...K), wherein T is the number of cooperative cells, and K is the number of users in the system, and further obtains the channel information Hi and the noise power σi2 of each user; S2, acquiring the complementary channel H̅i of each user on the basis of the channel information Hi of each user, and conducting channel expansion for each complementary channel H̅i to obtain a matrix H̿={ H̅i,σi/}, wherein / is the unit matrix of formula I, and Mk represents the number of the receiving aerial of the user k; S3, conducting LQ decomposition for the matrix H̅i to obtain a unitary matrix Qi; S4 ...
