Blind multiband signal detection with multirate snapshots in low SNRs

•Different sampling rates result in different frequency locator polynomial evaluations.•Multiband Signal can be blindly detected even in SNR = −20dB.•Probability of false alarm is efficiently lowered. A novel multirate sampling scheme is proposed for wideband spectrum sensing. The signal is subsampl...
