In this paper, the information entropy is used to extract the single feature, which are power spectrum entropy, wavelet energy spectrum entropy, singular spectrum entropy and Renyi entropy. And then, the feature selection algorithm of distance measurement and Sequential Feature Selection(SFS) are presented to select the optimal feature subset. Finally, the BP neural network is used to classify the signal modulation. The simulation result shows that the four-different information entropy can be used to classify different signal modulation, and the feature selection algorithm is successfully used to choose the optimal feature subset and get the best performance.<\/jats:p>","DOI":"10.4018\/ijmcmc.2017070107","type":"journal-article","created":{"date-parts":[[2017,8,18]],"date-time":"2017-08-18T12:25:09Z","timestamp":1503059109000},"page":"90-111","source":"Crossref","is-referenced-by-count":3,"title":["Modulation Recognition of Digital Multimedia Signal Based on Data Feature Selection"],"prefix":"10.4018","volume":"8","author":[{"given":"Hui","family":"Wang","sequence":"first","affiliation":[{"name":"College of Information and Communication Engineering, Harbin Engineering University, Harbin, China"}]},{"given":"Li Li","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Information and Communication Engineering, Harbin Engineering University, Harbin, China"}]},{"given":"Yun","family":"Lin","sequence":"additional","affiliation":[{"name":"College of Information and Communication Engineering, Harbin Engineering University, Harbin, China"}]}],"member":"2432","reference":[{"key":"IJMCMC.2017070107-0","doi-asserted-by":"publisher","DOI":"10.1093\/bioinformatics\/btp630"},{"key":"IJMCMC.2017070107-1","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.2016.2620435"},{"key":"IJMCMC.2017070107-2","doi-asserted-by":"publisher","DOI":"10.1109\/18.923723"},{"key":"IJMCMC.2017070107-3","doi-asserted-by":"publisher","DOI":"10.1109\/ICACC.2010.5487142"},{"key":"IJMCMC.2017070107-4","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2013.11.024"},{"key":"IJMCMC.2017070107-5","first-page":"329","article-title":"Time\u2013frequency complexity and information.","author":"P.Flandrin","year":"1994","journal-title":"Proc. of ICASSP \u201994"},{"key":"IJMCMC.2017070107-6","first-page":"1157","article-title":"An introduction to variable and feature selection.","volume":"3","author":"I.Guyon","year":"2003","journal-title":"Journal of Machine Learning Research"},{"key":"IJMCMC.2017070107-7","doi-asserted-by":"publisher","DOI":"10.1023\/A:1012487302797"},{"key":"IJMCMC.2017070107-8","first-page":"(9), 4483-4498","article-title":"Palmprint recognition based on complete direction representation.","author":"W.Jia","year":"2017","journal-title":"IEEE Transactions on Image Processing"},{"key":"IJMCMC.2017070107-9","first-page":"312","article-title":"A comparison of time- frequency analysis methods and their applications.","volume":"04","author":"D.Jianhua","year":"2007","journal-title":"Journal of Engineering Geophysics"},{"key":"IJMCMC.2017070107-10","first-page":"31","author":"Z.Jiguo","year":"2012","journal-title":"Vijay P.
