Cooperative Spectrum Sensing for Geo-Location Databases
2012Spectrum sensing techniques are the key components for identifying and exploiting unused radio spectrum resources in the perspective of the cognitive radio paradigm. Based on the centralized cooperative sensing techniques, vast generalized databases named geo-location databases (GL-DB) can be deployed in order to centralize sensing and general radio ...

Coalition Formation and Spectrum Sharing of Cooperative Spectrum Sensing Participants
IEEE Transactions on Cybernetics, 2017In cognitive radio networks, self-interested secondary users (SUs) desire to maximize their own throughput. They compete with each other for transmit time once the absence of primary users (PUs) is detected. To satisfy the requirement of PU protection, on the other hand, they have to form some coalitions and cooperate to conduct spectrum sensing.

Bandwidth-Efficient Cooperative Spectrum Sensing
2012Cooperative spectrum sensing can achieve better detection performance by enabling Cognitive Radio (CR) users to report local sensing information for further combining. In the initial setup phase that the CR users are performing spectrum sensing, idle communication channels without the licensed user signal have not been well identified and the reporting

Cooperative compressive wideband power spectrum sensing
2012 Conference Record of the Forty Sixth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2012Compressive sampling is a popular approach to relax the rate requirement on the analog-to-digital converters and to perfectly reconstruct wideband sparse signals sampled below the Nyquist rate. However, there are some applications, such as spectrum sensing for cognitive radio, that demand only power spectrum recovery. For wide-sense stationary signals,

Cooperative spectrum sensing for mobile users
2008 IEEE 16th Signal Processing, Communication and Applications Conference, 2008Cognitive radio is a radio communication technique, where unlicensed or cognitive users monitor the spectrum for the existence of licensed (primary) users and have a communication capability when the primary users donpsilat transmit their data. This technique needs an effective spectrum sensing because of the not disturbing the primary users.

Cooperative spectrum sensing with energy harvesting
Telecommunication Systems, 2019In cognitive radio networks, secondary nodes should sense the channel using spectrum sensing algorithms to detect primary activity. When primary user (PU) is idle, secondary users opportunistically transmit over this frequency hole. In this paper, we provide the detection probability (DP) of the energy detector (ED) for wireless energy harvesting ...

Cooperative spectrum sensing in LTE networks
2014 IEEE 27th Canadian Conference on Electrical and Computer Engineering (CCECE), 2014Expanding the new technologies such as Long Term Evolution (LTE) has caused spectrum scarcity. Spectrum sensing can help LTE find other available frequencies to use as secondary user. There are many solutions to enhance the spectrum sensing. In this paper, we are looking at frequency bands in TV broadcasting spectrum as a suitable candidate to be used ...

Cooperative spectrum sensing in cognitive networks
TENCON 2008 - 2008 IEEE Region 10 Conference, 2008In cognitive networks, cooperative spectrum sensing is employed to detect the presence of primary user quickly. The difference of sensing performance between totally cooperative networks and partially cooperative networks (network cooperation gain) is studied in this paper.

Optimization of Cooperation Sensing Spectrum Performance
2009 WRI International Conference on Communications and Mobile Computing, 2009Cooperation spectrum sensing in cognitive radio networks has an analogy to a distributed decision in wireless sensor networks, where each sensor make local decision and those decision result are reported to a fusion center to give the final decision according to some fusion rules.

An energy-efficient cooperative spectrum sensing
2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2015In this work, the energy consumption in the cooperative spectrum sensing is analysed. The analysis also covers the detection quality assessment and the definition of the energy efficiency (EE) metric. It is shown how cooperation among the sensing nodes affects the EE and how relaying of sensing information and node selection influences the detection ...
