作者： Xin-yu Liu Na Dong Jian-fang Chang Dong-hui Li Ai-guo Wu Academy of Electrical and Information Engineering Tianjin University

In PCB circuit detection system, it is necessary to locate and measure elements accurately. For the circular electronic elements in PCB, this paper proposes a localization method based on artificial bee colony（abc） algorithm. In this method, the three-point method is introduced to correspond a circle with an individual in bee colony, so that the circles are located though bee colony’s search. The first step of circle localization method is extracting the edge in PCB images with the canny operator, then the abc algorithm is used to search the circles. The mean gray values of the candidate circles are defined as fitness *** the guidance of the fitness function, the proposed method can locate an optimal circle in an iteration. In every iteration,the method needs delete the already located circles to prevent that the circles are located repeatedly until all circular electronic elements are located. Experiments show that the method can locate the circular electronic elements with shorter execution time and higher accuracy to meet industrial needs.

Joint power and spectrum allocation in multi-hop cognitive radio networks

引用

The Journal of China Universities of Posts and Telecommunications 2014年第2期21卷 9-14页

作者： WU Jing LI Yi LIU Gang JI Hong School of Telecommunication Engineering Beijing University of Posts and Telecommunications

Various cognitive network technologies are developed rapidly. In the article, the power and spectrum allocation in multi-hop cognitive radio network （CRN） with linear topology is investigated. The overall goal is to minimize outage probability and promote spectrum utility, including total reward and fairness, while meeting the limits of total transmit power and interference threshold to primary user simultaneously. The problem is solved with convex optimization and artificial bee colony （abc） algorithm jointly. Simulation shows that the proposed scheme not only minimizes outage probability, but also realizes a better use of spectrum.

关键词： cognitive radio power allocation outage probability spectrum utility abc algorithm
