Wideband Autonomous Cognitive Radios: Spectrum Awareness and PHY/MAC Decision Making
… new ways of better utilizing the scarce wireless spectrum resources. The CRs have been made feasible by recent advances in software-defined radios (SDRs), smart antennas, reconfigurable radio frequency (RF) front-ends, and full-duplex RF front-end architectures, to name a few. Generally, a CR is …

Spectrum Awareness: Deep Learning and Isolation Forest Approaches for Open-set Identification of Signals
… need systems to identify the signals within a spectrum environment. In this thesis, we extend current research in the area of signal identification by using previous work in the area to construct a deep learning-based classifier that is able to classify a signal as either as a communication …

Spectrum-Aware Orthogonal Frequency Division Multiplexing
… radio concept has quickly evolved to include spectrum sensing, awareness, and cognitive algorithms for machine learning resulting in the cognitive radio model. This work explores the application of reconfigurable hardware to the physical layer of cognitive radios using non-contiguous …

Exploiting Cyclostationarity for Radio Environmental Awareness in Cognitive Radios
… of wireless digital communications has raised spectrum shortage and security issues. In particular, the need for new spectrum is the main obstacle in continuing this growth. Recent studies on radio spectrum usage have shown that pre-allocation of spectrum bands to specific wireless …
