摘要： A reception station 1b compares its BSSID with BSSID included in a signal that has arrived thereat. As BSSIDs included in signals transmitted by interfering stations 1c and 1d both match BSSID of the reception station 1b, the reception station 1b identifies each of the interfering stations 1c and 1d as a non-suppression target transmission source. As neither of BSSIDs included in signals transmitted by interfering stations 2a and 2b matches BSSID of the reception station 1b, the reception station 1b identifies each of the interfering stations 2a and 2b as a suppression target transmission source. The reception station 1b uses characteristic amounts of signals that are associated with the interfering stations (i.e., suppression target transmission sources) 2a and 2b and that have been measured in the past as characteristic amounts of interfering signals that are used to suppress the interfering signals from a received signal.

摘要： When communicating with a second wireless station, a first wireless station judges, based on link-related information received form the second wireless station and link-related information extracted from a signal transmitted by a fourth wireless station, whether a transmission link from the third wireless station to the fourth wireless station and a transmission link from the first wireless station to the second wireless station can be concurrently established without interference with each other. If judging affirmatively, the first wireless station transmits a signal to the second wireless station in synchronization with a signal transmitted by the third wireless station to the fourth wireless station. Preferably, when the first wireless station having a concurrent transmission control function communicates with the second wireless station having a interference reduction function, the first wireless station controls the interference reduction function of the second wireless station based on the link-related information received from the second wireless station and interference information, such that the transmission link from the third wireless station to the fourth wireless station and the transmission link from the first wireless station to the second wireless station can be established at the same time without interference with each other. If judging that the concurrent transmission is available, the first wireless station transmits a signal to the second wireless station according to a timing that overlaps transmission of a signal from the third wireless station to the fourth wireless station.

摘要： At a time T131, a wireless communication apparatus 11A determines to transmit a data packet, and then performs interference signal detection for a period TA. At a time T132 preceding a time T133 at which the period TA has elapsed since the time T131, the wireless communication apparatus 11A detects a data packet d21 (an interference signal). At a time T134 at which a period TB has elapsed since the time T132 at which the interference signal has been detected, the wireless communication apparatus 11A starts transmitting a data packet d11 to a wireless communication apparatus 12A. At a time T136, the wireless communication apparatus 11A completes the transmission of the data packet d11.

摘要： A diversity receiver carries out error detection, error correction, and data detection on each detected data string 21. An output switching unit 17 outputs a decoded data string 24 of a branch selected by a branch selector 16. The branch selector 16 selects a branch of highest priority in priority information 29 from branches of which a data detection signal 25 indicates that the data is valid and of which the number of error symbols 22 coincides with a minimum value. In the priority information 29, higher priority is assigned to a branch that includes an antenna of which the coverage is closer to that of an antenna included in a branch selected at the immediately-previous time. Thus, selected from the plurality of branches having the minimum number of error symbols 22 is the one that includes the antenna of which the coverage is closest to the coverage of the antenna included in the branch selected at the immediately-previous time. Therefore, it is possible to suppress the occurrence of misselection of a poor-quality branch, and improve a reception characteristic.
