An interference elimination method provided herein includes: the ith transmitter of a group transmitters obtains an interference vector of each user, where: the interference vector of the kth user is Hkiwim; obtains at least L−N linear combinations for each user, wherein: the linear combination includes linear combinations of aligned interference vectors and linear combinations of N−Lk interference vectors, N is the number of receiving antennas of the user, and L is a sum of the signal flows of all users; the pre-coding vectors of all transmitters is obtained according to the linear combinations of all users; and the signals pre-coded using the pre-coding vectors are sent. Accordingly, a data transmitting apparatus is provided herein.
