Cognitive radio (CR) is a promising solution for an efficient usage of both wideband and
narrowband spectrum. Compressive sensing (CS) paradigm is one of the methods that can …

The spectrum sensing problem has transformed significantly with the emergence of
cognitive radio and opportunistic spectrum access concepts. These developments have …

Spectrum Sensing is the fundamental and essential operation in Cognitive Radio (CR) to
find the unused frequency bands. To detect the unused spectrum, different types of detectors …

The article investigates the complexities associated with spectrum analysis in cognitive radio
networks (CRNs). It begins by acknowledging the evolving challenges of spectrum sensing …

The paper describes a centralized cooperative spectrum sensing system, implemented on
Universal Software Radio Peripheral (USRP) hardware platforms driven by the Genuinely …

Orthogonal Frequency Division Multiplexing based modulation schemes has the advantage
of reducing ISI in Cognitive Radios (CR). An OFDM modulation scheme for CR, with QAM …

The study of present day, the spectrum usage reveals that nearly 70% of available spectrum
is underutilized which is a serious concern as the available spectrum is the most precious …

The deficiency of the spectrum range is major issue in communication technology to
augment the new standard of communication. The reuse of spectrum is become a way to …

Cognitive radio is an intelligent radio network that has the capability of recognizing when the
spectrum is idle and unused by the licensed users to allot those frequencies to unlicensed …

In wireless communication, a potentially new technology is cognitive networking. This
networking is simply a communication system which is very intelligent and consists of …
