Title:
INTERFERENCE OFFSET METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/179759
Kind Code:
A1
Abstract:
Disclosed are an interference offset method and device, which relate to the technical field of communications, and are used for offsetting interference in data received by a receiving device, and improving the reliability of data transmission. The method provided in the embodiments of the present invention comprises: receiving a first signal; acquiring an interference offset matrix, wherein the interference offset matrix contains M interference offset vectors, each of the interference offset vectors contains Nr interference offset coefficients, and the relevancy between each of the interference offset vectors and an interference feature vector of any interference source of N interference sources on Nr receiving antennas is less than a first pre-set threshold value, where M is the number of pre-set interference offset vectors, and N is the number of pre-set interference sources; and multiplying the interference offset matrix by the first signal, and demodulating the multiplied signal to obtain a data stream.
