    摘要: Disclosed is a wireless communication system and the like that can avoid interference even if a plurality of networks coexist. The wireless communication system includes a primary user, cluster head equipment, and a secondary user. The cluster head equipment is for providing a local area network to a cluster region containing the abovementioned primary user. Also, the cluster head equipment contains: an acquisition means that acquires one or both—of information regarding the primary user and information regarding a primary signal—and the like; and a transmission means that transmits information to the secondary user. Then, using this wireless communication system, the secondary user performs cognitive wireless communication or the like on the basis of the information received from the transmission means of the cluster head equipment.

    摘要: There is disclosed a channel adjusting method capable of suppressing the occurrence of interference between a cognitive pilot channel (CPC) and an auxiliary control channel (ACS) in cognitive wireless communications. According to the channel adjusting method for use in cognitive wireless communications, initially, a connection using a cognitive pilot channel (CPC) is set up. Thereafter, it is determined whether or not a spectrum sensing channel (ACS) is to be utilized. If yes, it is then determined whether or not any interference occurs between the spectrum sensing channel (ACS) and the set-up cognitive pilot channel (CPC). This allows an adjustment to be performed such that no interference occurs between the cognitive pilot channel (CPC) and the spectrum sensing channel (ACS).

    摘要: Provided is a spectrum sensor for cognitive wireless communication whereby it is possible to improve communication efficiency. In a cognitive wireless communication system, a spectrum sensor senses spectra in multiple frequency bands. A spectrum sensor is configured to be able to operate in one operation mode selected from among a spectrum sensing mode for sensing spectra, and a communication mode for communicating with a wireless communication device. Further, the spectrum sensor is provided with a controller for controlling the operation mode. The controller switches between the above-mentioned operation modes during the symbol period of an ultra-wideband physical layer (UWB PHY).

    摘要: An interference preventing method prevents communication interference between two or more wireless communication networks having mutually different physical layers, in which wireless communication is performed between a plurality of devices and a coordinator. By using a coordinator of each of the wireless communication networks, a scanning period for scanning a coexistence notification signal that is transmitted from a coordinator of another wireless communication network for a predetermined period is arranged before a first super frame immediately after input of power. The CB of the coordinator is transmitted at least once or more for one super frame, and, in a case where the CB transmitted from the coordinator of the other wireless communication network is acquired during the scanning period, control for preventing communication interference with the other wireless communication network is performed.
