Title:
BEAM-FORMING METHOD, SIGNAL TRANSMITTER AND SIGNAL RECEIVER
Document Type and Number:
WIPO Patent Application WO/2017/206527
Kind Code:
A1
Abstract:
Disclosed in the present invention is a beam-forming method, comprising: a signal transmitter acquiring a downlink pilot symbol sequence and an MUB codebook, and weighting the downlink pilot symbol sequence on the basis of the MUB codebook to obtain a downlink pilot symbols collection; transmitting the downlink pilot symbols collection on all antennae during pilot frequency weighting cycles, and receiving a pre-coding matrix instruction set sent by a signal receiver; calculating a reconstructed channel feature eigenvector according to the pre-coding matrix instruction set, and beam-forming downlink data according to the reconstructed channel feature eigenvector. The present invention may improve the accuracy of directional beams, and reduce beam leakages between users. Also provided are a signal transmitter and a signal receiver which may be used to achieve the described beam-forming method.
