    摘要: A transmitter and transmission method for preventing a call failure using a system power value, caused by rapidly increasing transmit power against a large phase mismatch occurring before a phase mismatch correction cycle elapses in a smart-antenna communication system. In the transmitter and transmission method, if the system power value is higher than a power threshold, a radiation pattern similar to a common beam channel pattern is created.

    摘要: An apparatus is provided for receiving channel quality information (CQI) in a mobile communication system in which a mobile station feeds back downlink CQI over a CQI transmission channel. In the apparatus, a power correlation estimator correlating code values mapped to tiles, wherein the CQI transmission channel includes a plurality of the tiles distinguished by time and frequency resources. A maximum detector detects CQI corresponding to a code value having the maximum power correlation value among estimated power correlation values. A threshold comparator compares the detected CQI with a CQI threshold, and outputs the detected CQI as final CQI if the detected CQI is greater than or equal to the threshold.
