Satellite communication on the forward link is inherently broadcasted, ensuring access to many devices in remote areas. The satellite systems are expected to take a game-changing role in the development of the Internet of Things (IoT) and Mobile Edge Caching (MEC) sectors by providing efficient multicast content delivery schemes. However, in a multi-user, multi-spot beam High-Throughput Satellite (HTS) or Very High-Throughput Satellite (VHTS), several strategies and adaptations are required for integrating multicast networks with a satellite communication system for efficiency and reliability. Many techniques are discussed here, including efficient link adaptation for multicast flows, an adaptation of multicast control protocols over space link, and the provision of necessary ground system designs to support beam multicast capability on next-generation reconfigurable payload satellites. An elegant approach for multicast support in a wholesaler/reseller network is suggested to allow for services from different operators through the same IPv4/IPv6 multicast address. A group key-based scalable conditional access system is proposed. A technique is captured that converts the plurality of live HTTP unicast video streams of the same event to a multicast stream for a resource-efficient transport over the satellite.","PeriodicalId":401042,"journal":{"name":"38th International Communications Satellite Systems Conference (ICSSC 2021)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131092390","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}

BGAN provides almost global coverage with three geostationary satellites for maritime, enterprise, aviation, and governmental customers. BGAN uses a proprietary Inmarsat Air Interface-2 (IAI-2) protocol stack, which is also the basis of the technical specification of the SL (Satellite Link) family of the Satellite Universal Mobile Telecommunications System (S-UMTS) standard, which was proposed by Inmarsat and published by ETSI as TS 102 744 [2-5]. Unlike IAI-2, S-UMTS Family SL is an open standard. In this paper, a system level simulator that models the S-UMTS Bearer connection and Bearer control layers is presented. In particular, the focus is on the return link scheduling utilizing adaptive modulation and coding scheme (MCS) to balance reliability and efficient bandwidth usage. A custom algorithm was designed for the return link radio resource management (RRM) of the S-UMTS simulator.","PeriodicalId":401042,"journal":{"name":"38th International Communications Satellite Systems Conference (ICSSC 2021)","volume":"8 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127402576","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 general, space grade digital devices are used for onboard digital processor to mitigate soft error caused by radiation effect. On the other hand, commercial grade devices achieve higher processing speed at a lower price than space grade devices even though less resilient. Therefore, it is expected to install it in onboard digital payload utilizing a variety of soft error mitigation techniques. Conventionally, soft error can be mitigated utilizing TMR (Triple Modular Redundancy) and periodic refreshment. However, these techniques increase circuit scale, and it is difficult to avoid burst errors arising during a refresh period. Therefore, this paper proposes a novel error tolerant digital processing technique utilizing stochastic computing. Furthermore, the effectiveness of the proposed technique is verified through simulation results. We confirm digital channelizer utilizing the proposed technique is more tolerant of soft error than TMR and achieve the required SNR (Signal to Noise power Ratio) of 30dB.","PeriodicalId":401042,"journal":{"name":"38th International Communications Satellite Systems Conference (ICSSC 2021)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132823188","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 a multi-beam high throughput satellite (HTS) system with colour reuse, channel induced impairments are not limited to noise but include substantial intra-system colour reuse interference that corrupts the intended signal. In this article, I examine HTS system channels, signals and interferers, and derive the HTS system Shannon channel capacities in theory. In the process, I clarify the theoretic foundation for the interference Gaussian distribution assumption from information theory perspective which is missing in the HTS capacity literature. I then apply probability theory to obtain average channel capacities over traffic and mobility caused interference power level uncertainties. The work extends original Shannon capacity theory to the HTS systems which allows HTS channel and system capacity estimation without the costly measurements data. It completes the study by including sample examples from a simulated HTS system with a user service coverage area of continental US to showcase the application of the theoretic development. The paper complements and refines the studies on the topic in similar works in the HTS literature.","PeriodicalId":401042,"journal":{"name":"38th International Communications Satellite Systems Conference (ICSSC 2021)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130884293","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}
