SPECTRUM SENSOR FOR COGNITIVE WIRELESS COMMUNICATION AND METHOD FOR COGNITIVE WIRELESS COMMUNICATION

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 (1) 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 (51) for controlling the operation mode. The controller (51) switches between the above-mentioned operation modes during the symbol period of an ultra-wideband physical layer (UWB PHY).
