    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.

    摘要翻译： 接收站1b将其BSSID与包括在已经到达的信号中的BSSID进行比较。 由于由干扰站1c和1d发送的信号中包括的BSSID都匹配接收站1b的BSSID，所以接收站1b将每个干扰站1c和1d识别为非抑制目标传输源。 由于由干扰站2a和2b发送的信号中包括的BSSID都不与匹配接收站1b的BSSID，所以接收站1b将每个干扰站2a和2b识别为抑制目标传输源。 接收站1b使用与干扰站（即，抑制目标发送源）2a和2b相关联的信号的特征量（即，抑制目标发送源）2a和2b，并且作为用于抑制干扰信号的干扰信号的特征量， 接收信号。

    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： A master device transmits a beacon signal including information related to a proximity wireless communication area in a predetermined cycle by using a transmission power which allows the beacon signal to reach beyond the proximity wireless communication area. When a slave device receives the beacon signal from the master device, the slave device estimates a distance to the master device in accordance with the information of the beacon signal. When a wireless communication terminal is located within the proximity wireless communication area, the slave device is connected to the master device by using a proximity wireless communication.

    摘要： In this signal detection device (100), a delaying unit (101) delays a first distributed signal or a second distributed signal distributed from a received signal for a period of time of T1 to form a first multiplication signal, and delays the one for a period of time of T2 (T2>T1) to form a second multiplication signal. An integrator (104) calculates a first correlation value by integrating the result of multiplying the first distributed signal and the first multiplication signal. An integrator (105) calculates a second correlation value by integrating the result of multiplying the second distributed signal and the second multiplication signal. An evaluation unit (108) evaluates whether the signal to be detected, which is a periodic signal with a period of T1 or a periodic signal with a period of T2, exists or not, on the basis of the first correlation value and the second correlation value.
