However, the RS codes have two drawbacks: 1) Received erroneous codewords may not be detected by the RS decoders; 2) The RS decoders may produce a codeword that difiers from the transmitted codeword. In the implementation of erasures-and-errors decoding, such drawbacks may cause the RS codes to provide incorrect erasure information to other RS codes, resulting in unreliable burst-error correction performance of the HDS. In order to combat the drawbacks, we propose a new three-dimensional code in which Cyclic Redundancy Check (CRC) codes are applied; we call this new code as the 3DRS-E and CRC code (3DRS-EC). Experimental results show that the 3DRSEC can signiflcantly decrease the probability of the drawbacks, thereby improving the error-correction performance of HDS systems.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126267335","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}

In order to obtain time-frequency energy information accurately, flrstly, the original signal is transformed by wavelet. From the viewpoint of energy, using adaptive threshold for denoising, while most of the signal energy is reserved, the in∞uence of most noise is eliminated at the same time. Then, LMD is used to get the signal component which has deflnite physical sense and contains fault information. To identify the abnormal frequency components, the signal component is analyzed in time-frequency domain. Finally, the running state of hydro turbine can be diagnosed by analyzing the time-frequency information of each component signals. This method is applied in the No.1 hydro turbine of a power plant, the analysis shows that this method is efiective, and the running state of the turbine can be correct evaluated.","PeriodicalId":213716,"journal":{"name":"The Journal of Information and Computational Science","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126488628","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}
