Subjected to a hard constraint on the quality-of-service (QoS) requirements and the capability of relay, the admission problem could be described as the problem of maximizing the amount of subcarriers saved by relaying transmission. With further consideration of the user's selection of relays and the competence among users, several new algorithms were proposed. Meanwhile, the application in multi-service scenario was taken into account, and the effect caused by the ratio of services with different transmission rate requirements was studied. Simulation results verify that the presented algorithms can obtain more admitted users, less block probability and more saved subcarriers, thus effectively enhancing the system capacity and resource utilization.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121026781","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}

We focus on the fact that the second-order modes of all-pass digital filters are all unity. As a result, it is clarified that the minimum L2-sensitivity realization of an all-pass digital filter is equal to the balanced realization, of which closed form expression can be derived analytically.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116368301","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 paper proposes an improved side information generation scheme of transform domain distributed video coding considering a novel content-based side information refinement technique, which is performed with the color and texture features to segment the side information into different regions with different reliance. Then the low-reliance regions' side information could be corrected by 3-D recursive search. In addition, an adaptive overlapped block motion compensation technique is implemented to improve performance on the base of results from the content-based approach. Experiments illustrated that a significant improvement of performance has been achieved by the proposed approach compared to the cases without it.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126015476","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 can be performed using the PIM-SM multicast routing architecture which enable IP multicast routing on existing IP networks. The RP is required for network running PIM-SM, and the RP location changes the efficiency of multicast data packets. In general, the PIM-SM is consisted of a shared tree for keep-alive packets and a source-based tree for sending out large data. Therefore, the RP utilization is very high when the access network uses PIM-SM. And PIM-SM protocol cannot be applied in different architectures with access networks such as PON, HFC. In this paper, we propose a new PIM-SM protocol which reduces processes of traditional PIM-SM protocol in IPTV services. The proposed a new PIM-SM protocol can reduce the number of processes for RPT configuration and can deliver multicast data packets immediately through the SPT. Therefore, the RP utilization in extended PIM-SM improves than traditional PIM-SM.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"93 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130364865","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 we develop a novel algorithm based on the theory of Kolmogorov complexity to identify the coding type of Chinese characters of a given text segment. An array of text compressors are used as filters to evaluate the information distance of text under examination and the training corpus coded in different coding type. The information distance can be used to decide the coding type according to the Kolmogorov theory. In this paper a particular compressing algorithm is used to minimize computing complexity by separating coding book training stage and compressing stage. Finally, we present the experimental results through which the accuracy and performance of the algorithm is confirmed. The result also proves that this algorithm is especially efficient when short text segment is under examination comparing with the n-gram algorithms.","PeriodicalId":348778,"journal":{"name":"2010 2nd IEEE InternationalConference on Network Infrastructure and Digital Content","volume":"414 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116557986","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}
