In general the SI-SAP offers an agnostic interface to whichever SD layer is used. So QoS provision in the BSM architecture has to face the issue of traversing the SI-SAP interface by means of standardized signalling, which shall enable on one side maintaining compatibility with existing QoS functions required in the IP layers and above, and on the other side communication to the lower layer entities deputed to QoS accomplishment. This paper presents this QoS framework for both DiffServ, and RSVP/IntServ, focusing attention on the key concept of QIDs (queue identifiers) and on the way to handle them. In the BSM architecture QIDs represent abstract queues, each with a defined class of service, for transfer of IP packets to the SD layers.","PeriodicalId":137382,"journal":{"name":"2008 IEEE International Workshop on Satellite and Space Communications","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127665130","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}

However at Ka band frequencies and above an adaptive physical layer wherein the physical layer parameters are dynamically modified on a per user basis is necessary to counteract atmospheric attenuation. Satellite radio resource management (RRM) at the medium access control (MAC) layer has become an important issue given the emphasis placed on quality of service (QoS) provided to the users. The work presented here tackles the problem of Satellite RRM for broadband satellite systems using DVB-RCS where a fully adaptive physical layer is envisaged at Ka band frequencies. The impact of adaptive physical layer and user traffic conditions on the MAC layer functions is analyzed and an algorithm is proposed for the RRM process. Various physical layer issues associated with the resource management problem are also analyzed.","PeriodicalId":137382,"journal":{"name":"2008 IEEE International Workshop on Satellite and Space Communications","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121578070","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}

XCP aims mainly at avoiding congestion. However, in GEO satellite access network, XCP is also expected to offer fairness between data flows, a better bandwidth use and a quite stationary throughput per flow. Then, the two main points of this work are to propose a satellite network architecture based on XCP and to study the behaviour of XCP compared to a classical TCP in this context (through NS2). Nevertheless, all of our expectations are not encountered: XCP shows several limits, highly induced by the high delay of GEO systems and low bandwidth. Eventually, the paper discusses the use of XCP as a resource manager for IP networking satellite systems.","PeriodicalId":137382,"journal":{"name":"2008 IEEE International Workshop on Satellite and Space Communications","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132882564","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 first analyze the impact of channel estimation performance when synchronization time drifts in general OFDM system. The analysis will show that channel estimation performance is degraded in transient region of time synchronization. When channel estimation process is initialized, channel estimation performance is degraded. This is because that channel estimation process should be initialized when synchronization time is changed. We then show how proposed algorithms can reduce the performance degradation of channel estimation. Results of simulation show that the utilization of proposed algorithms can reduce the performance degradation of channel estimation. Proposed algorithms can be utilized in both high speed and low speed OFDM system. Above all, the use of proposed algorithms prevents burst error that is harmful for general communication network system.","PeriodicalId":137382,"journal":{"name":"2008 IEEE International Workshop on Satellite and Space Communications","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127312916","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 show that a channel state model that uses a Markov state model of order one is not appropriate if the state duration is of high importance, which can be the case in the process of system planning. In this case, a dynamic higher order Markov state model can be used. We study the modeling of the channel state duration for both single and multiple satellite broadcasting systems. In case of multiple satellite systems the channel state modeling is performed based on a dynamic higher order Markov channel state model for joint processes that depends on the current state duration. This approach is able to model the channel states of the whole system correctly, as well as the channel states of each satellite observed independently, showing the ability of capturing the state correlation between multiple satellites. Moreover, we introduce a reduced complexity channel state generation algorithm based on the PDF of the state duration. Our channel state models are validated with measurements of the Satellite Digital Audio Radio Services (S-DARS) system XM Radio carried out on various locations in the USA and Canada.","PeriodicalId":137382,"journal":{"name":"2008 IEEE International Workshop on Satellite and Space Communications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125753207","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}
