In this paper, we propose a novel cooperative sensing method by iteratively improving the sensing ability. The proposed method can increase the number of cooperative sensing nodes. Moreover the harmful interference can be avoided, even if the sensing information of each sensing node is transmitted at the same spectrum of the primary system. In general, the cooperative sensing ability depends on the number of the cooperative nodes providing sensing information. If these pieces of information are…

Study on Cooperative Sensing in Cognitive Radio based AD-HOC Network
A soft decision based cooperative sensing method for cognitive radio (CR) in ad-hoc networks where test statistic used in traditional single user energy detection is treated as soft decision information and has better performance compared to non-cooperative sensing.
Optimal Linear Cooperation for Spectrum Sensing in Cognitive Radio Networks
This paper proposes an optimal linear cooperation framework for spectrum sensing in order to accurately detect the weak primary signal and proposes a heuristic approach, where a modified deflection coefficient that characterizes the probability distribution function of the global test statistics at the fusion center is proposed.
Soft Combination and Detection for Cooperative Spectrum Sensing in Cognitive Radio Networks
It is shown in this paper that an SNR wall reduction can be achieved by employing cooperation among independent cognitive radio users and a new softened hard combination scheme with two-bit overhead for each user is proposed to achieve a good tradeoff between detection performance and complexity.
Optimization for Cooperative Sensing in Cognitive Radio Networks
It is shown that cooperating all secondary users in the network does not necessary achieve the optimum performance, but instead, it is achieved by cooperating a certain number of users with the highest primary user's signal to noise ratio.
Cooperative Sensing among Cognitive Radios
This work proposes light-weight cooperation in sensing based on hard decisions to mitigate the sensitivity requirements on individual radios and shows that the "link budget" that system designers have to reserve for fading is a significant function of the required probability of detection.
Implementation issues in spectrum sensing for cognitive radios
To improve radio sensitivity of the sensing function through processing gain, three digital signal processing techniques are investigated: matched filtering, energy detection and cyclostationary feature detection.
