N2 - The detection of bandlimited (BL) constant magnitude (CM) signals in white noise of unknown power is analyzed. This is relevant in the context of Dynamic Spectrum Access since Wireless Microphones (WM) typically use analog FM modulation when transmitting in the TV bands, and their bandwidth is much smaller than that of a TV channel. Although detectors exploiting either the BL or the CM properties have been presented in the literature, these two features have not been jointly considered yet. We derive the Generalized Likelihood Ratio test for this setting. Performance is evaluated in the framework for WM simulation developed to assist the IEEE 802.22 Working Group.
