By a News Reporter-Staff News Editor at Telecommunications Business -- Data detailed on Networks - Wireless Communications and Networks have been presented. According to news reporting originating from Zhejiang, People’s Republic of China, by VerticalNews correspondents, research stated, “Cooperative spectrum sensing has been studied to combat the hidden terminal problem by exploiting the spatial diversity in cognitive radio (CR) networks. This paper concerns blind cooperative spectrum sensing with soft fusion, where the a priori knowledge of channels and primary signals is unavailable, and soft information is transmitted from each secondary user (SU) to a fusion center for detection.”
Financial supporters for this research include National Natural Science Foundation of China, Australian Research Councils DECRA, Zhejiang Natural Science Foundation, K.C. Wong Magna Fund from Ningbo University.
Our news editors obtained a quote from the research from Ningbo University, “We first introduce the Quade test to design a blind detector. Then, a new detector with both lower computational complexity and lower overhead is derived, where only the estimated power and the variance of the instantaneous power at each SU are required at the fusion center. The analytical expressions for the detection performance, in terms of false-alarm probability and detection probability, are derived for the proposed detector. Simulation results are provided to validate the theoretical analyses and demonstrate the superior performance of proposed detector compared to the state-of-theart detectors.”
According to the news editors, the research concluded: “It is also shown that, with the increase of the number of hidden terminals in the CR, the proposed detector can maintain high detection performance while the conventional detectors exhibit rapid performance degradation.”
