Повний текст джерелаThis thesis addresses the error control problem for satellite links from the perspective of cross-layer design. At the crossroads of qos-related constraints, devices complexity and efficient spectrum use, error control is indeed a key aspect of wireless communications - particularly crucial in the satellite context - where cross-layer enhancements can play an important role. After a thorough introduction to cross-layer design, the first part of this work focuses specifically on the error control strategy of early DVB satellites, where redundancies between the channel decoder and the adaptation layers are set to light in order to propose a joint bandwidth-efficient error control policy. The focus then moves to second-generation DVB satellites and the definition of the novel, IP-centric and cross-layer friendly GSE encapsulation protocol, where results from the aforementioned study were successfully applied. Finally, a whole new cross-layer framework called HERACLES is introduced, offering efficient and overhead-free error correction capabilities for almost any layer of a protocol stack and being patented at the moment of writing these words. The results of the overall work show the strengths of an integrated approach to error control, and open the way for innovative cross-layer mechanisms to be deployed in next-generation communications networks

Повний текст джерелаThe characterization of the propagation channel is a major issue in order to optimize satellite communication systems. At Ka-band, or at higher frequency bands, signal attenuation is almost exclusively caused by the troposphere, and particularly rain, whose attenuation can reach levels preventing any communication. Frequency scaling is a technique aiming to determine the tropospheric attenuation at a target frequency, from measurements made at another frequency using a beacon receiver. This technique is useful to obtain precise attenuation statistics at a target frequency, or to determine in real time the attenuation on a satellite uplink, from a measurement of the attenuation on the downlink, in order to optimise fade mitigation techniques. This thesis activity consisted in studying, on the one hand, the sources of error affecting attenuation measurements, collected using beacon receivers, in order to quantify them, or even, if possible, to correct them. On the other hand, several promising frequency scaling models of the literature are reviewed, and improvements are considered. In particular, it is shown that frequency scaling models based on micro-physical modelling are of interest for tropical climates
