The likely use of Ka band and above frequencies for future satellite systems and the need for a better quality of service (QoS) complicate the radio resource management process especially in the return link of a satellite system, one that connects the user to the Gateway or Hub. This paper discusses the research themes that are part of the PhD research, carried out at SUPAERO, aimed at developing radio resource management algorithms that will ultimately improve the resource utilization and the QoS for the return link of interactive broadband satellite systems employing fade mitigation techniques at Ka/Q/V band frequencies. The inputs and optimization criteria for the resource management process are identified. Various physical layer issues that confront the process are also identified. The duration of the research is about 3 years from March 2007 to end of 2009.","PeriodicalId":286578,"journal":{"name":"2007 International Workshop on Satellite and Space Communications","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126521215","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 order to use the available spectrum more efficiently and to maximise the link reliability this paper presents the analysis of possible utilisation of LDPC decoder parameters to improve the performance of the DVB-S2 standard adaptive coding and modulation (ACM) procedures. A switching algorithm is proposed for selecting between the adjacent transmission schemes that is assisted by the information on the number of iterations and the number of violated parity checks in previous frames obtained from the iterative LDPC decoder. The simulation results are given in terms of BER curves and the belonging LDPC decoder's average number of iterations and average number of violated parity checks. These results, in particular the LDPC decoder's probability density function of the number of required iterations, are further compared with results obtained with a SNR estimation algorithm proposed in the literature for the use in DVB-S2. The comparison confirms that the LDPC decoder information can be efficiently utilised in ACM procedures.","PeriodicalId":286578,"journal":{"name":"2007 International Workshop on Satellite and Space Communications","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132186163","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}

Saratoga was developed by Surrey Satellite Technology Ltd (SSTL) for file transfers of imaging data recorded onboard the Internet-Protocol-Based Disaster Monitoring Constellation (DMC) satellites, and has been in operational use from low Earth orbit since 2004. Saratoga focuses only on efficient communication to the next hop when link connectivity is available, by filling the link with packets sent at line rate. This ensures that as much data as possible is transferred to the peering node during a twelve-minutes-or-less pass over a satellite ground station. Saratoga uses a minimal bandwidth-efficient negative acknowledgement mechanism to ensure reliable data transfer. We examine how Saratoga can be adapted to serve as an efficient convergence layer for delay-tolerant networking (DTN), by transferring DTN bundles as well as files. This will allow DTN networks to increase efficiency of communication across briefly-available disrupted links -for long-distance deep space links as well as for short-distance terrestrial mobile ad-hoc networks.","PeriodicalId":286578,"journal":{"name":"2007 International Workshop on Satellite and Space Communications","volume":"37 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114416998","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}
