In this paper, we present an algorithm for modulation classification designed for cooperative MIMO system based on pattern recognition approach. This is done using higher order statistics (HOS) features and a Bayesian network classifiers. In order to evaluate the effectiveness of Bayesian network methods, a comparative study is performed between the naive Bayes using discretization (NBD), the tree augmented naive Bayes (TAN) and the decision tree (J48) classifiers. Through the receiver operating characteristics (ROC) curves, the probability of identification and the training time, we show that the NBD and the TAN classifiers achieve nearly similar performance compared to the J48 classifier. Hence, these classifiers can be used to distinguish between different M-ary shift keying linear modulation types and thus lead to better monitoring of the intercepted signals in broadband technologies with low complexity.","PeriodicalId":264787,"journal":{"name":"2015 23rd International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126037220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Applying this by accordingly modifying the industry-standard simulator in the LTE FDD downlink environment, and adopting the performance thresholds coming out of common digital transmission standards, optimal CP length values were estimated as coming out of the compromise between the achieved performance and the so added data redundancy.","PeriodicalId":264787,"journal":{"name":"2015 23rd International Conference on Software, Telecommunications and Computer Networks (SoftCOM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116473527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
