The detection and classification of the Wireless Microphone signal in the IEEE 802.22 WRAN system

For the use of the IEEE 802.22 WRAN, the spectrum sensing of the TV band is essential. In this paper, the Testbed for the signal detection and sorting algorithm and verification was proposed among the spectrum sensing algorithm about the part 74 wireless microphone (WM) signal. In case a plurality of WM signals exists within 6 MHz bandwidth, this algorithm uses the polyphase filterbank and grasps the signal absence. And by using the cyclostationary property, it has the advantage of moreover accurately knowing with the number of WM signals and frequency location.
