One of the common problem that is faced during the medical treatment of the apnea is the undetermination of the efficiency of the applied treatment in terms of objective criteria. It is needed to automatically detect each snoring episode in order to estimate the spectral features and determine the snoring sound intensity. In this study, an automatic detection system of acoustic snoring signals has been designed, to work with long duration respiratory sound recordings. The system was designed to select snoring episodes from simple snorers and OSAS patients and to reject the undesired waveforms. The sound recordings were taken from patients that are suspected of OSAS pathology while they were connected to the polysomnography in Gulhane Military Medical Academy (GMMA) Sleep Studies Laboratory. In order to validate the system, 500 snores were analysed taken from 30 patients with different apnea/hypopnea index (AHI) . Results were compared with manual annotations done by a medical doctor and the average sensitivity of the system is determined as 86%","PeriodicalId":415037,"journal":{"name":"2006 IEEE 14th Signal Processing and Communications Applications","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125268843","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}

However, the performance of these systems for agglutinative languages is very low. The major reason for that is, the language models that are built on the words do not perform well for agglutinative languages. In this study, three different language models that consider the structure of the agglutinative languages are investigated. Two of the models consider the subword units as the units of language modeling. The first one uses only the stem of the words as units, and the other one uses stems and endings of the words separately as the units. The third model, firstly, places the words into certain classes by using the co-occurrences of the words, and then uses these classes as the units of the language model. The performance of the models are tested by using two stage decoding; in the first stage, lattices are formed by using bi-gram models and then tri-gram models are used for recognition over these lattices. In this study, it is shown that the vocabulary coverage of the system seriously affects the recognition performance. For this reason, models that use stems and endings as the modeling unit perform better since their coverage of the vocabulary is higher. In addition to that, a single-pass decoder that can perform single pass decoding over these models is believed to increase the recognition performance","PeriodicalId":415037,"journal":{"name":"2006 IEEE 14th Signal Processing and Communications Applications","volume":"157 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121482932","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 performances of both systems for different values of CFO are compared. Since the desired performance cannot be achieved by CFO tracking ability of conventional LMS for SC and MC systems used in time varying channels, a fuzzy logic based LMS (F-LMS) algorithm is proposed. CFO tracking performance with the proposed F-LMS algorithm becomes very close to the performance of RLS algorithm with a small and negligible increment in computational complexity. Computer simulations using conventional LMS, normalized LMS, modified LMS, variable step size LMS-DFE, B-LMS-DFE and conventional RLS-DFE algorithms are performed in SC systems. The same algorithms are also used in MC (OFDM) systems in which the channel is estimated in time domain then used in frequency domain channel equalizer. For performance comparisons, the HIPERLAN/1 (SC) and HIPERLAN/2 (OFDM) standards are used as the working platforms during simulations. The obtained and compared results are given in Section 3","PeriodicalId":415037,"journal":{"name":"2006 IEEE 14th Signal Processing and Communications Applications","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124952939","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}
