Due to the randomness of wind power and it is not controllable, wind power is intermittent and volatility. With the increase of proportion of wind power in power grid, control the influence of wind power to power grid system frequency stability, becomes the key to ensure system stability and reliability problems. To effectively explore the wind itself implied the inherent law of random variables, this paper employed weighted entropy uncertainty measure theory, put forward multiple signal fusion method based on weighted entropy, to measure random events of the role of wind power system, power grid events to the connotation of the single attribute weight. Describes the calculating process of this method through examples and computational results, shows the frequency of random events and the limit of the inner link, for the correct decision and the selection of treatment methods to provide the basis.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"70 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131724622","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 this paper, narrow-band interference suppression based on FFT transform is adopted to improving anti-interference performance of CDMA communication systems significantly. Probability and statistics search for interference signal is used in frequency domain, which increases the stability of anti-interference. This paper describes Mat lab simulation and FPGA implementation of the algorithm. Hardware experiments show that the algorithm can improve the performance of narrow-band interference suppression for the ordinary CDMA mobile phone about 25dB.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131205170","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}

As a non-invasive approach, acoustic diagnosis brings a much more comfortable and convenient experience to subjects than the gold standard, polysomnography (PSG). However, there is a more demanding need from doctors to find the variations of the upper airway (UA) during a long duration for OSAHS patients. Formant features have a good performance on indicating the structure variations of UA, which can be regarded as a resonance in the snoring generation model. In this paper, we proposed a long duration analysis method of snore related signals (SRS) method based on formant features. The first three formant frequencies (F1, F2 and F3) are extracted to group the long duration SRS data into different states with the help of K-means method. Each state of SRS data represents a degree of collapse in UA. We found that formant features have distinguished values in different states and the transition possibility calculated by Hidden Markov Models (HMM) between each state is helpful for analysis of long duration SRS data. This method could be effective in analysis of variations in UA for OSAHS patients and establishment of long duration SRS database.","PeriodicalId":285687,"journal":{"name":"2013 International Conference on Information Technology and Applications","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115572294","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}
