Abstract
(EN)
The present invention relates to a blind adaptive beamforming algorithm and especially relates to a blind adaptive beamforming algorithm applied to a half-duplex passive UHF RFID system. The algorithm innovatively proposes a concept of iteration so that compared with the original method, necessity and complexity of channel estimation are reduced, the operating process is simple, costs of system operation are greatly reduced and in addition, efficiency is improved.
