<p>An interference cancellation method includes: the interference vectors of each user are obtained by a transmitting terminal (S101); at least L-N linear combination relationships are obtained for each user, wherein said linear combinations are those of the aligned interference vectors and other interference vectors (S102), wherein N is the number of user receiving antennae, and L is the sum of the user signal streams; the pre-encoding vectors of all transmitting terminals are obtained according to the linear combination relationships of all users (S103); and the signals pre-encoded by the pre-encoding vectors are transmitted (S104). A data transmission device is also provided.</p> |
