  • Characterization of the Attenuation due to Rain Cell Fields applying Cellular Automata to Weather Radar Images

    Publication Year: 2006, Page(s):3 - 7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5176 KB) | HTML iconHTML

    A straightforward linkage between rain cell dynamics in terms of reflectivity Z (dBz) or its equivalent rain rate R (mm/h) and satellite or terrestrial radiolink attenuation can be performed. This work focuses on the presentation of an approach for assessing and characterizing rain cell dynamics based exclusively on the analysis of the radar reflectivity scans recorded in weather radar image, and ...

    For regenerative telecom satellite systems, the turbo decoder has become a basic component of the on-board processing (OBP). This paper presents the algorithm selection choices and the test bench policy during the design process of a communication system critical block such as a turbo decoder compliant with the DVB-RCS standard (digital video broadcast-return channel satellite). The architecture, ... View full abstract»

  • Frequency-Hopping Techniques for Secure Satellite TT&C: System Analysis & Trade-Offs

    Publication Year: 2006, Page(s):13 - 17
    Cited by:  Papers (6)

    Near future on-board telemetry, tracking and command (TT&C) equipment for secure communications will likely adopt frequency hopping (FH) instead of direct sequence (DS) spread spectrum (SS) techniques. As far as TT&C systems will have to cope with jammer-to-signal power ratios higher than 50 dB, classical DS approaches must be abandoned in favour of more robust FH solutions. In the followi...

    In this paper, a class of discrete Radon transform, namely, finite Radon transform is proposed for the first time as a new technique in the realization of the orthogonal frequency division multiplexing (OFDM). The Radon transform is chosen in the OFDM structure to serve as a data mapper instead of the conventional data mapping techniques like the phase shift keying (PSK) mapping, in a way that ens...

  • Depolarization Mitigation using Frequency Offset in the Dual-Polarized X-Band for EESS

    Publication Year: 2006, Page(s):25 - 28
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5205 KB) | HTML iconHTML

    Dual-polarization frequency reuse technique has been actively adopted in space-to-earth links for earth exploration satellite service (EESS) to meet growing demands on high rate data transmission over the restrictedly allocated bandwidth in X-band. However, the performance of the dual-polarization system is affected by depolarization due to tropospheric propagation impairments such as rain drops a... View full abstract»

  • Jointly Optimal Routing and Resource Allocation in Hybrid Satellite/Terrestrial Networks

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5138 KB) | HTML iconHTML

    In the future hybrid satellite/terrestrial networks, efficient routing at network layer and allocation of resources at link layer will have to be performed in order to satisfy traffic requests and minimizing at the same time the cost of the allocated bandwidth among the heterogeneous network components. This simultaneous routing and resource allocation (SRRA) problem can be specified in the framew... View full abstract»

  • Optimal key scheduling for secure satellite broadcasting to mobile users

    Cryptography will be the most suitable technique to protect the access to subscribed added-value services for mobile applications provided through satellite broadcasting (e.g., localization and mobile TV). Although satellite broadcasting allows provision of the service even in remote locations, it may also prevent small mobile devices from sending feedback to the satellite when no special return l...

  • TCP Hybla Performance in GEO Satellite Networks: Simulations and Testbed

    Publication Year: 2006, Page(s):41 - 45
    Cited by:  Papers (2)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5819 KB) | HTML iconHTML

    TCP connections that incorporate satellite links are greatly disadvantaged with respect to entirely wired connections, because of their longer round trip times (RTTs). TCP Hybla has been conceived with the primary aim to solve this problem, therefore it appears quite promising in geostationary (GEO) satellite environments, where the long propagation time greatly affects the RTT. In order to compar... View full abstract»

    The TCP-friendly rate control for small packets (TFRC-SP) protocol was designed for applications including streaming audio and voice over IP which send small packets. The long round trip delay of a satellite link could degrade the performance of such applications including streaming audio and VoIP that use TFRC-SP. In this paper, we analyze the performance of TFRC-SP carrying live streaming audio ... View full abstract»
