Received: 9 January 2019 Accepted: 20 March 2019 Cognitive radio (CR) technology is an emerging technology that overcomes the scarcity and poor utilization of spectrum resources. Under the constraint of system energy, this paper puts forward a cooperative spectrum sensing algorithm to minimize the sensing overhead, considering the mutual relation between sensing duration and the number of cognitive users. The simulation results show that, when the selected cognitive users face the same mean… Expand

TLDR
This paper proposes an optimal sensing framework for the IEEE 802.22 wireless regional area networks (WRANs) that directs the base station to manage spectrum sensing by constructing each primary signal's spatial profile of received signal strengths as a detection criterion. Expand

There are new system implementation challenges involved in the design of cognitive radios, which have both the ability to sense the spectral environment and the flexibility to adapt transmissionExpand
In-band spectrum sensing in cognitive radio networks: energy detection or feature detection?
TLDR
It is shown that energy detection under lognormal shadowing could still perform well at the average SNR < SNRwall when collaborative sensing is used for its location diversity. Expand
Sensor Selection for Cooperative Spectrum Sensing

A Novel Physical Layer Security Scheme in OFDM-Based Cognitive Radio Networks
TLDR
A physical-layer-security scheme for an underlay relay-based cognitive radio network (CRN) that uses orthogonal frequency-division multiplexing (OFDM) as the medium access technique is proposed and an algorithm is also proposed for subcarrier mapping at the forwarding relaying node. Expand
Resource allocation for OFDM-based multiuser cooperative underlay cognitive systems
TLDR
The simulation results show that the proposed scheme achieves higher secondary and sum rates compared to existing approaches with perfect CSI and the robustness of the proposed algorithm when the secondary user has only partial information about channel gains is derived. Expand
