  • Mobile station and antenna verification controlling method for mobile station
    Patent number: 8694038
    Abstract: Antenna verification is controlled in the ON state at least until transmission to a wireless base station is started, and particularly, a result of estimation of the signal phase individually from two antennas of the wireless base station is reflected on a reception signal process, to decrease the failure rate in synchronism establishment arising from that antenna verification of transmission diversity to be carried out for reception characteristic enhancement of the downlink is controlled in the OFF state in order to enhance the throughput characteristic as in a case wherein the HSDPA is applied.
    Type: Grant
    Filed: May 15, 2009
    Date of Patent: April 8, 2014
    Assignee: Fujitsu Limited
    Inventors: Yusuke Shinoda, Hiroyuki Ataka, Daiki Chou
