摘要： A base station broadcasts a message saying that transmittable ranging codes are limited by antenna IDs to limit antennas and the ranging codes to be searched, thereby reducing a processing load of the search. In a cellular radio communication system in which a base station device is connected to plural antennas, and antenna IDs for identifying the antennas are transmitted from the respective antennas, the base station device broadcasts a message saying that a group of ranging codes transmittable by a terminal device is limited by the antenna IDs, the terminal device receives the message, identifies the antenna ID, selects the ranging code from the group of the ranging codes corresponding to the antenna ID, and transmits the selected ranging code.

摘要： A discontinuous change in a transmission timing in a time domain, which is caused by a transmission timing adjustment processing of an OFDMA uplink or the like, brings about a discontinuous rotation of a signal phase in a frequency domain, resulting in reduced communication quality. A wireless communication system of the present invention allows the signal phase of the frequency domain in a receiving station to be continuous before and after the timing adjustment processings by controlling a signal sequence in a transmission signal after conversion in the time domain in synchronization with the timing adjustment processing.

摘要： To provide a space multiplex signal detection circuit capable of obtaining an excellent error rate characteristic by suppressing an increase in the circuit scale if when a modulation multivalued number is particularly increased in the case of receiving a signal subjected to space multiplexing to detect the signal. SOLUTION: A transmission signal candidate narrow-down circuit 108 refers to a proximity signal point data table 109 and stepwise narrows down the number of a plurality of transmission signal candidates to a prescribed number of the candidates. The proximity signal point data table 109 stores the cross-reference between signal points closer on a transmission constellation to signal points of transmission signals of each of transmission systems estimated by a transmission signal estimate circuit 107. A maximum likelihood estimate circuit 113 receives candidates of the transmission signal sequences and metrics corresponding to the candidates and outputs a transmission signal sequence whose metric value is least as a final transmission signal sequence.
