  • Multi-antenna network system and signal processing method thereof
    Patent number: 10511356
    Abstract: A multi-antenna network system has a reduced operational complexity for matrix inversion by referring to the variations of the status of a plurality of communication channels at a first time duration and a second time duration. Therefore, the speed for calculating matrix inversion is improved. Accordingly, the amount of servo antennas and/or user antennas operating in the same multi-antenna network system can be increased.
    Type: Grant
    Filed: November 27, 2017
    Date of Patent: December 17, 2019
    Assignees: ALPHA NETWORKS INC., INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE
    Inventors: Chia-Lung Liu, Dong-Shing Wu, Ren Hao Chen
