Cooperative Spectrum Sensing Based on Dempter-Shafer Theory of Evidence in Cognitive Radio Network
Published 2013-08-01“…Cognitive radio has the advantage of high spectrum utilization since the spectrum can be shared by primary and secondary user.Meanwhile,the new adaptable characteristic is required for the secondary user.On the basis of analyzing D-S theory of evidence,a novel distributed cooperative spectrum sensing scheme was presented,which modified the combination equation for conflicting evidence source,and the BPA function based on fuzzy degree calculation was redefined.Simulation results show that the proposed scheme can sense the available spectrum in the cognitive radio networks very well,and can be used as a general spectrum sensing scheme in AWGN and Rayleigh fading channel when compared with the traditional "and","or" fusion rules and other D-S theory of evidence schemes in the previous literature.…”

Construction and application of Anhui Unicom enterprise big data platform
Published 2018-01-01“…The challenges and opportunities faced by Anhui Unicom of big data construction,and the experience of Anhui Unicom rapidly constructing B+O convergent smart operation platform which realized multi-dimensional and multi-level fusion management of cross-domain platform were summarized.In addition,the customer off-grid prediction was also deeply studied by Anhui Unicom.Achieving the off-grid prediction model through the big data platform which made the precision ratio get 90% and the recall ration get 9%.On the other hand,the big data platform has been popularized to other departments by integrated applications,such as,user awareness enhancement etc.Internal operation efficiency was improved and NOC (network operations center) was transformed to SOC (service operations center).…”

Multipurpose watermarking realizing image copyright notification,copyright protection and content authentication
Published 2009-01-01“…A multipurpose image watermarking scheme based on chaotic systems and sub-image lifting wavelet transformation(LWT) was proposed.Firstly, the host image was divided into 8×8 sub-images and each sub-image was performed 2-level LWT.Then, the invisible watermarks for copyright protection and content authentication were respectively embedded into low and intermediate frequency LWT components of some sub-images that were randomly selected by general Arnold map.A new kind of quantization technique was adopted in the embedding process and the extracting process was blind.Secondly, the visible watermarks for copyright notification were embedded into the image spatial domain based on image fusion method, in which the embedding coefficients were generated by the 4D hyperchaotic sequences.Experimental results were presented, showing that the proposed watermarking scheme is effective.…”

Method of improving big data value density based on heterogeneous association
Published 2017-12-01“…The big data resources possessed by telecom operators are usually distributed in many different systems,such as DPI、OIDD、CRM.Moreover,the formulation,interpretation and rules of the big data are not always the same in different systems.Therefore,it is difficult to identify and utilize the same object’s multi-type data in different sys-tems.Big data analysis’ sample size and dimension are limited,with the decreasing of analysis results’ reality and accuracy.The methods,architectures and implementation examples of big data’s heterogeneous association were pre-sented.The data fusion in user-dimension from different systems could optimize the data sample space of applications,such as user portrait.Thus,the value of carrier’s big data density was greatly improved.…”
