Cognitive radio (CR) has emerged as a promising technology to exploit the unused portions
of spectrum in an opportunistic manner. The fixed spectrum allocation of governmental …

Dynamic spectrum policies combined with software defined radio are powerful means to
improve the overall spectral efficiency allowing the development of new wireless services …

Cognitive radio (CR) technology is envisaged to solve the problems in wireless networks
resulting from the limited available spectrum and the inefficiency in the spectrum usage by …

We define a cyclostationary signature as a feature which may be intentionally embedded in
a digital communications signal, detected through cyclostationary analysis and used as a …

Cognitive radio networks have been recognized as a promising paradigm to address the
spectrum under-utilization problem. To improve spectrum efficiency, many operations such …

In a cognitive radio network (CRN), in-band spectrum sensing is essential for the protection
of legacy spectrum users, with which the presence of primary users (PUs) can be detected …

Cognitive radio (CR) technology enables the opportunistic use of the portions of the licensed
spectrum by the CR users, while ensuring low interference to the primary user (PU) activity …

Establishing a control channel for medium access control is a challenging problem in multi-
channel and dynamic spectrum access (DSA) networks. In the design of multi-channel MAC …

Spectrum bands are the backbone of wireless networks. Every user is allocated a fraction of
the spectrum from available fixed spectrum band. But, the fixed available spectrum band …

In decentralized cognitive radio (CR) networks, enabling the radios to establish a control
channel (ie," rendezvous" to establish a link) is a challenging problem. The use of a …
