摘要: Wideband spectrum sensing which requires detecting the presence or absence of signals in a wideband channel faces multiple practical issues. Current bandwidth limitations state-of-the-art analog to digital converters require alternative approaches be considered for sensing. Cyclostationary feature detection is promising tool robust noise, and takes advantage noise stationarity. In this paper, we propose cyclostationary detector that operates on sub-Nyquist samples obtained via either multicoset sampling modulated converter front-end, present receiver's performance at low SNRs.
