On the other hand, for the adaptive observer the wind speed is considered as an unknown parameter. A free Linux-based real time platform was used for the experimental setup.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121577437","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}

This work consists in introducing an energy storage element linked to the three-phase inverter by means of a dc/dc bidirectional converter. This dc/dc converter works as a ¿buck¿ converter while the battery is recharged or as a ¿boost¿ converter when the battery supplies the load. The aim of this configuration is to reduce the bulky and heavy of the batteries bank. The new system (inverter, dc/dc converter and battery) has to work then in one of the following two modes according to the availability of the electric system: as an active power filter and battery charger if the grid is available, or as an APS and boost if the grid is unavailable.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122526625","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}

Many events occur in the body during this state. In the past, significant efforts have been made to provide clinicians with reliable and less intrusive tools to automatically classify the sleep stages and detect apnea events. A few systems are available in the market to accomplish this task. However, sleep specialists may not have full confidence and trust in such systems due to issues related to their accuracy, sensitivity and specificity. The main objective of this work is to explore possible relationships among sleep stages and apneic events and improve on the accuracy of algorithms for sleep classification and apnea detection. Electroencephalogram (EEG) and Heart Rate Variability (HRV) will be assessed using advanced signal processing approaches such as Detrend Fluctuation Analysis (DFA). In this paper, we present a compendium of features extracted from EEG and Heart Rate Variability (HRV) data acquired from twenty five patients (21 males and 4 females) suffering from sleep apnea (age: 50 ± 10 years, range 28–68 years undergoing polysomnography). Polysomnographic data were available online from the Physionet database. Results show that trends detected by these features could distinguish between different sleep stages at a very significant level (p≪0.01). These features could prove helpful in computer-aided detection of sleep apnea.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128346772","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}

BER performance maintenance at high data rates in cognitive radio 认知无线电高数据速率下误码率性能维持

This booming technology of dynamic spectrum allocation, popularly known as cognitive radio has setup new horizons in the field, to explore and to work on. Cognitive radio is envisioned as the ultimate system that can sense, adapt and learn from the environment in which it operates. Sensing the higher bandwidth an SDR (Software defined radio) in a Cognitive System, tunes the circuits in the System for transferring data at higher data rates. At such increased data rates the BER (Bit Error Rate) performance may degrade. So it is a must for the SDR to accordingly add processing circuits to maintain the BER. One such option has been explored and worked on. It is by using the FHSS (Frequency Hopping Spread Spectrum technique) that one can maintain the BER performance at increased data rates. Earlier work includes the use of higher bandwidth available for increasing the coding bits and thereby making the data more secure. In other words availability of higher bandwidth in Cognitive radio can be utilized either to increase the actual data rate (Yet maintain the BER) or to improve the BER performance & maintain the original data rate. Results of FHSS implementation by Matlab M-file programming and improved BER performance by adaptive coder both have been depicted in the paper. In fact present paper is an outcome of the doctoral research on Error Control Coding for performance improvement in BER.","PeriodicalId":236039,"journal":{"name":"2010 20th International Conference on Electronics Communications and Computers (CONIELECOMP)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129170829","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}
