Energy harvesting (EH) and spectrum harvesting (SH) are two promising and useful green
communication and networking mechanisms for the next-generation wireless networks …

Cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) is the most widespread
multicarrier modulation scheme. However, the use of a rectangular filter in CP-OFDM causes …

The cyclostationary spectrum (CS) method is one of the best at what it does because it
effectively detects idle spectrum with low signal-to-noise ratios (SNR). In order to distinguish …

Spectrum sensing is a challenging issue in cognitive radio network. In particular, wideband
spectrum sensing gains more attention due to emerging 5G wireless networks characterized …

Quickest change detection (QCD) is a fundamental problem in many applications. Given a
sequence of measurements that exhibits two different distributions around a certain flipping …

As the essential technology of cognitive radio networks, numerous spectrum sensing
approaches have been established to date. However, some spectrum sensing methods …

The growing prominence of spectrum sharing technologies has spurred interest in spectrum
monitoring technologies with the ability to identify unknown wireless signals. This paper …

In congested electromagnetic environments, cognitive radios require knowledge about other
emitters in order to optimize their dynamic spectrum access strategy. Deep learning …

In shared spectrum with multiple radio access technologies, wireless standard classification
is vital for applications such as dynamic spectrum access (DSA) and wideband spectrum …

In this paper, we propose a novel low-complexity scheme to extract cyclic features of
wideband signals from sub-Nyquist samples as Nyquist rates push contemporary analog-to …
