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.

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 a case where it is determined that communication data indicates a first data attribute in a transmitter, that communication data is transmitted and an acknowledgement signal is requested to be sent back from a receiver. If the acknowledgement signal is not sent back, that communication data is retransmitted. In a case where it is determined that the communication data indicates a second data attribute in the transmitter, that communication data is transmitted and an acknowledgement signal is requested to be sent back according to an allowable number of retransmissions corresponding to the second data attribute. And that communication data is retransmitted in accordance with the allowable number of retransmissions and presence or absence of the acknowledgement signal sent back. The allowable number of retransmissions corresponding to the second data attribute is smaller than that corresponding to the first data attribute.

摘要： A method for determining a measurement time period for measuring a propagation environment in a wireless station set having a plurality of wireless stations, between which wireless communication is made using a channel selected from a plurality of channels different in frequency. The method includes the steps of: obtaining a measurement time period in another wireless station set having a plurality of wireless stations; and determining the measurement time period in the own wireless station set so as to have a time period that does not overlap the obtained measurement time period.

摘要： The present invention relates to a wireless LAN (Local Area Network) communication system. Upon a timer unit 108 clocking a predetermined time T after an access point 100 has transmitted a beacon signal 200, a transmission frame control unit 105 generates a CTS frame 301, and transmits an error frame 401 via a transmission frame generation unit 106, a wireless transmission unit 107 and an antenna 109. Accordingly, upon receiving the CTS frame 301, a communication terminal 20 ceases transmitting data for a NAV (Network Allocation Vector, transmission prohibition interval) period in accordance with IEEE 802.11 standard.

摘要： When the communication channel is to be changed, a more optimal communication channel is determined by summing up the results of measuring communication states transmitted from individual wireless terminals A, B, and C and making a collective judgment. Weighting coefficients are set to the individual wireless terminals A, B, and C. Values indicating whether or not the respective communication states of the individual wireless terminals are optimal with channels ch1 to ch4 to be used for communication (which are, e.g., 1, 0, 1, 2 with the respective channels ch1, ch2, ch3, and ch4 for the wireless terminal A and larger as the communication states are less optimal) are multiplied by the weight coefficient (the value of 3). The resulting values are summed up on a per-channel basis and the most optimal communication channel (of which the summed value is lowest) is selected. As a result, wave interference with the other wireless terminal is reduced.
