Different types of digital filters are used to remove signal components from unwanted frequency ranges. It is difficult to apply filters with fixed coefficients to reduce random noises, because hum behaviour is not exact known depending on the time. Adaptive filter technique is required to overcome this problem. In the article two types of adaptive filters are considered. Results of simulations in MATLAB are presented. Filters were coded in MPLAB C compiler and tested on a digital signal processor of microchip family dsPIC30f6014, based on the results of modeling.","PeriodicalId":295946,"journal":{"name":"2008 IEEE Region 8 International Conference on Computational Technologies in Electrical and Electronics Engineering","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115254930","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}

It has become a standard to use Shupepsilas nonreciprocity formula for calculating the thermally induced bias error in fibre gyroscopes. This effect is initiated by thermal waves propagating through the material. However, the Shupe formula does not describe the effect of homogeneous, but transient heating of the fiber coil, which leads to an inhomogeneous deformation of the fibers and thus to nonreciprocity. Furthermore, the effect of inertial forces such as vibrations has been described first in the work of Mohr and Schadt (2004) and shall be extended in this contribution. Wepsilall describe a simulation model of the fiber coil using analytical and - where necessary - finite element methods. Finally, wepsilall verify our simulation model with measurement results from an FOG.","PeriodicalId":295946,"journal":{"name":"2008 IEEE Region 8 International Conference on Computational Technologies in Electrical and Electronics Engineering","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115782285","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 composite wireless network is assumed to be operated by either a single or several operators. End-user terminals in P1900.4 are generally assumed to be multimode/multihoming, supporting several RATs and with multi-radio link capabilities, also possessing some cognitive radio capability such as flexible operation in different frequency bands. There are, however, conceivable scenarios where the P1900.4 standard would still be applicable even if terminals possessed limited such capabilities. At the core of the IEEE P1900.4 standard, Reconfiguration Management Entities (RMEs) are defined, located on terminal and network sides. The network side RME manages the terminal indirectly, but by providing/collecting context information and providing Radio Recourse usage policies to terminals. The terminal side RME makes final decisions regarding selection of the most appropriate RAT/RAN, band, etc., thereby also triggering the corresponding radio link reconfigurations in the terminal. Of course, all such decisions made by the terminal RME must be within the remit of policies conveyed by the network RME. This paper introduces the activities and work under progress within the IEEE P1900.4 working group.","PeriodicalId":295946,"journal":{"name":"2008 IEEE Region 8 International Conference on Computational Technologies in Electrical and Electronics Engineering","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115135353","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}
