Abstract—Signal detection is of interest in spectrum awareness that is useful for future cognitive military radios for their spectrum usage decisions.

Detecting signals using known spectrum is generally referred to as a spectrum matching or a spectrum (shape) feature detector. As far as the authors know, ...

This paper studies window based detectors where window shapes can be matched for the expected spectrum.

Abstract—Recently, radar frequency bands have been drawing much attention as possible candidates for cognitive radio, since their utilization was revealed ...

In spectrum sensing, the goal is to meet a given “receiver operating characteristic” (ROC) constraint at very low SNR. Classical detection theory suggests that ...

Abstract. The correlation detection and adaptive line spectrum enhancement(ALE) algorithm in weak signal detection is presented. Aiming at the problem that ...

We propose to use stochastic resonance, a nonlinear filter having certain resonance frequency, to detect primary users when the SNR is very low. Both block and ...

Nov 29, 2021 · In the present study, we further extended low-SNR event detection based on the spectral matrix analysis with the wavelet analysis and time delay coordinate.

Jul 6, 2022 · This paper aims at spectrum measurement at low SNR in the presence of uncertainty in noise with the help of double thresholds that can adapt its value ...
