STBC-PC is applied to this study in order to employ STBC with single antenna which is incorporated in any wireless portable devices, e.g., mobile stations and to achieve high gain. The path selection algorithm is designed to be used at the mobile station where is assumed to have the knowledge of all channel gains, hence it can be designed to maximize the channel capacity and to provide better network performance. The simulation results have been shown that the cooperative transmission with STBC-PC can achieve BER of 10–4 at the level of SNR about 17 dB which is lower level than the cooperative transmission without STBC-PC. Moreover, the proposed method can provide BER of 10–2 at SNR of 3 dB which is lower level the STBC-PC-based cooperative transmission without path selection.","PeriodicalId":287775,"journal":{"name":"2011 Eighth International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128935327","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}

The TBWC algorithm was developed to enhance a classification performance of a clustering algorithm. In the experiments, five datasets were used to evaluate the predictive performance. The experimental results show that the TBWC algorithm yields the highest accuracies when compared with decision tree learning and clustering for all datasets. In addition, this algorithm can improve the predictive performance especially for multi-class datasets which can increase the accuracy up to 36.67%. Finally, it can reduce attributes up to 59.82%.","PeriodicalId":287775,"journal":{"name":"2011 Eighth International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121376930","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}
