The implementation of those security services in WLANs presents a complex and challenging environment because these services may deplete the limited network resources and increases the burden of supporting the quality of service for multimedia applications. As an alternative solution, we thus introduce a new security system, which is based on RCNC (random connection node convolutional) code and m-sequence. The architecture of RCNC code formed by developing the conventional convolutional code structure has an excellent security operation as well as an error correction function. To verify the performance of our proposed system, the computer simulations have been performed in IEEE 802.11b environment.","PeriodicalId":434986,"journal":{"name":"2004 IEEE Region 10 Conference TENCON 2004.","volume":"228 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121309442","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 is based on discrete P, PI and PID control algorithm, and does not require complex mathematical models or large look up tables. The scheme is implemented by using a TMS320F2812 digital signal processor. The real-time experimental results given in this paper show that the speed control method proposed could provide accurate speed control and over a wide range of speeds, and can also perform accurately at different operating conditions (steady state/transient operation under soft chopping mode). The closed-loop SRM speed control system is seen to achieve /spl plusmn/0.01 speed accuracy, depending on the needed operating speed range, with a step response settling time of 0.25 to 1.05 seconds. Complete descriptions of the experimental system, along with software operating instructions, are presented.","PeriodicalId":434986,"journal":{"name":"2004 IEEE Region 10 Conference TENCON 2004.","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127205812","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}

With parallel in space scheme, power system is split into several subsystems. The bottlenecks in distributed computation are the low speed network communication and the mass times of boundary values exchange for subsystem time domain step solution. For that the iterative boundary values convergence property is the key factor to affect the efficiency, three boundary values methods (BVM) is presented to improve the subsystem solution convergence property. With the BVM, the necessary exchanging times of boundary values are reduced, the communication times for one time domain step is shorten and the distributed computation efficiency is improved.","PeriodicalId":434986,"journal":{"name":"2004 IEEE Region 10 Conference TENCON 2004.","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125178069","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}

To support the development of such complex algorithms, computational power of digital signal processors (DSP's) increased tremendously. This lead to DSP's enriched with dedicated hardware support for various application specific features. The software development tools and compiler support has also improved to a large extent. This has slashed down the effort time in implementing the speech codecs. On the other hand, the cost of development tools may be prohibitive for non-vendors and at times high level code conversion tools may not be present at all. This paper emphasizes on the implementation methodology and optimization techniques commonly used to realize such systems where codec implementation in all assembly is necessary. The codec that was chosen for implementing these techniques was the GSM half rate (GSM HR) speech codec. The techniques described here are not limited to only one speech codec but are applicable to any kind of speech codec.","PeriodicalId":434986,"journal":{"name":"2004 IEEE Region 10 Conference TENCON 2004.","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123702934","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}

Range sensors are applied to give linear distance and angle information while the welding torch attached to the robot is moving over surface of the workpiece.

Similar types of degradation can take place when the signal array response is known precisely but the training sample size is small. In this paper, on the basis of constrained-LMS (CLMS) algorithm, we propose a robust constrained-LMS (RCLMS) algorithm. Our robust constrained-LMS algorithm provides excellent robustness against the desired signal mismatches, offers fast convergence rate and makes the mean output array SINR consistently close to the optimal one. Computer simulations show better performance of our RCLMS algorithm as compared with the classical CLMS algorithm.","PeriodicalId":434986,"journal":{"name":"2004 IEEE Region 10 Conference TENCON 2004.","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126920619","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}
