ZERO-FORCING BEAMFORMING DEVICE AND METHOD THEREFOR BASED ON K-REGULARITY IN MULTIPLE INPUT SINGLE OUTPUT BROADCAST CHANNEL

摘要

Disclosed are a zero-forcing beamforming device and a method therefor based on k-regularity in a multiple input single output (MISO) broadcast channel. The zero-forcing beamforming device can comprise: a storage unit which stores channel information and the number of antenna to be selected by a data stream (RF chain); and a control unit which, based on the stored channel information and the stored number of antenna, optimizes zero-forcing beamforming by removing rows enabling a best performance for a remaining matrix, which is obtained by removing rows from a matrix of the channel information until the number of rows is the same as the number of antenna, one by one, or by removing rows enabling a minimum performance degradation for a matrix, which is obtained by removing rows from the matrix of the channel information until the number of rows is the same as the number of antenna, one by one.;COPYRIGHT KIPO 2015
