Coverage extension and service continuity can be provided considering satellites as additional components in future networks by allowing vertical handover to terrestrial radio interfaces. In this paper, the properties of Filter Bank Multicarrier (FBMC) as potential MC transmission scheme is discussed taking into account the requirements for the satellite-specific PHY-Layer like non-linear distortions due to High Power Amplifiers (HPAs). The performance for specific FBMC configurations is analyzed in terms of peak-to-average power ratio (PAPR), computational complexity, non-linear distortions as well as carrier frequency offsets sensitivity (CFOs). Even though FBMC and OFDM have similar PAPR and suffer comparable spectral regrowth at the output of the non linear amplifier, simulations on link level show that FBMC still outperforms OFDM in terms of CFO sensitivity and symbol error rate in the presence of non-linear distortions.","PeriodicalId":192172,"journal":{"name":"2014 7th Advanced Satellite Multimedia Systems Conference and the 13th Signal Processing for Space Communications Workshop (ASMS/SPSC)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122876829","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}

On the one hand, conventional transparent satellites are severely constrained by the available bandwidth for the feeder link, while, on the other hand, regenerative satellites require a very large on-board computational effort. An interesting alternative approach is to perform aboard the satellite a digital transparent processing to reduce the redundancy of the signals before transmitting them on the feeder link, hence improving the spectral efficiency of the feeder link with respect to a transparent satellite, while reducing at the same time the associated computational effort with respect to a regenerative satellite. Our results show that the signal occupancy on the feeder link can be effectively reduced, and this positively impacts the number of beams served by a given ground station, hence on the number of required ground stations for a multi-beam system with a large number of beams.","PeriodicalId":192172,"journal":{"name":"2014 7th Advanced Satellite Multimedia Systems Conference and the 13th Signal Processing for Space Communications Workshop (ASMS/SPSC)","volume":"174 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133350615","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}

At the same time, power consumption minimization is another important issue for network management. Consequently, the ideal goal is to maximize the QoE and, meanwhile, to minimize the power transmitted by network nodes. In telecommunications networks QoE is often linked to the transmission rate assured to a given application. Actually higher guaranteed transmission rate, lower packet loss, delay and jitter, which have a direct impact on QoE. In this view the requirement of maximizing QoE and minimizing power consumption conflict with each other because higher is the transmit rate better the QoE but higher required transmitted power. By taking the session time of a web navigation as a reference metric, in this paper, the authors propose a transmission rate allocation algorithm for satellite networks aimed at finding a satisfactory compromise between QoE and Transmitted Power (TP). Earth stations communicate with a satellite by using a common channel with an overall available transmission rate of RTOT. The allocation algorithm is formulated starting from the Multi Objective Programming theory and the Lp-problem and it is called Lp-problem based Rate Allocation (LpRA). Numerical results show that LpRA assures satisfying operative compromise between QoE improvement and power saving.","PeriodicalId":192172,"journal":{"name":"2014 7th Advanced Satellite Multimedia Systems Conference and the 13th Signal Processing for Space Communications Workshop (ASMS/SPSC)","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124629814","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 achieve this `anywhere anytime' communication in a global multi-beam satellite network with many gateways (GWs), the challenges of beam, gateway and satellite handovers faced by the satellite terminals mounted on mobile platforms such as long haul flights, global maritime vessels and continental trains must be adequately dealt with. Network-based localised mobility protocol proxy mobile IPv6 (PMIPv6) where the IP mobility procedures are relocated from the mobile nodes to the network components has been defined by the IETF for terrestrial networks. This paper proposes how the concept of PMIPv6 could be used to support IP mobility in a mesh regenerative multi-beam satellite network. What makes this proposed approach different from that defined by the IETF is the absence of tunnelling throughout the system and the difference in the roles played by the mobility agents.","PeriodicalId":192172,"journal":{"name":"2014 7th Advanced Satellite Multimedia Systems Conference and the 13th Signal Processing for Space Communications Workshop (ASMS/SPSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120975574","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}

The efficient usage of the spectrum in the satellite return link is a challenging task, especially if multiple users are present. In previous works Multi-User Detection (MUD) techniques have been widely studied to increase the spectral efficiency of the satellite return link. However, due to the high computational complexity and its sensitivity to synchronization and channel estimation errors, only few implementations of MUD for satellite communications exist. In this paper a novel Graphics Processing Unit (GPU)-based Software Defined Radio (SDR) implementation of a MUD receiver for transparent satellite return link is presented, which uses iterative channel estimation and decoding. The implementation can cope with the presence of strong phase noise. In addition to its high flexibility and low cost, with the GPU acceleration our SDR MUD receiver implementation achieves a decoding throughput of 270 Kbps using a single GPU card.","PeriodicalId":192172,"journal":{"name":"2014 7th Advanced Satellite Multimedia Systems Conference and the 13th Signal Processing for Space Communications Workshop (ASMS/SPSC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121041509","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}
