Cooperative spectrum sensing (CSS) is the key function of cognitive radio (CR) system to identify available spectrum. However, nature aggregating data makes CSS offer opportunities for Byzantine attackers undermine CR. In this letter, on basis a generalized soft attack model, we theoretically analyze strategies in absence any defense, terms strength and probability. Further, introduce classical trust-value based algorithm conduct evaluate security attackers, with aim providing guideline...
In an interweave cognitive radio system, cooperative spectrum sensing has been recognised as a key technology to enable secondary users opportunistically access licensed band without harmful interference primary users. At the same time, unmanned aerial vehicle equipped with and data transmission facilities is gaining more popularity in different applications. An vehicle-based investigated which used user, but unlike participation of multiple traditional sensing, virtual model introduced into...
In the field of cognitive radio (CR), cooperative spectrum sensing (CSS) utilizes spatial diversity each secondary user (SU) to accurately detect hole. Although information exchange and decision fusion in CSS improves accuracy, it also brings additional communication overhead energy consumption. Since SUs is limited, necessary improve performance while reducing consumption, i.e., maximizing efficiency (EE). this paper, two effective bitwise differential voting rules (DVRs) are proposed...
High accuracy and real-time Doppler frequency estimation in deep space is essential for spacecraft ranging, orbit determination planetary atmospheric measurement. Considering the problems of frequent lose-lock, high processing cost performance degradation current systems, an open-loop tracking system guided by on-line self-calibrating trajectory model proposed to achieve estimation. It includes a guidance predict target changing signal dynamic compensation reduce residual complexity,...
A hybrid algorithm is proposed to decrease the integration phase measurement error accumulation in open‐loop Doppler receiver which designed for space orbit determination and positioning applications when cooperated closed‐loop system unavailable. Firstly, adaptive‐neuro‐fuzzy inference (ANFIS) module α implemented interrupted data prediction. Then improve prediction accuracy of ANFIS , an adaptive Kalman filter employed fusion with predicted from complementation corrections. Meanwhile, β...
