Non-Orthogonal Transmission Techniques for Multibeam Satellite Systems

Beam Hopping Techniques in Multibeam Satellite Systems

A Decomposition Method for Frequency Assignment in Multibeam Satellite Systems

To comply with the continually growing demand for multimedia content and higher throughputs, the telecommunication industry has to keep improving the use of the bandwidth resources, leading to the well-known Frequency Assignment Problems (FAP). In this article, we present a new extension of these problems to the case of satellite systems that use a multibeam coverage. With the models we propose...

Adaptive Transmission Techniques for Mobile Satellite Links

Adapting the transmission rate in an LMS channel is a challenging task because of the relatively fast time variations, of the long delays involved, and of the difficulty in mapping the parameters of a time-varying channel into communication performance. In this paper, we propose two strategies for dealing with these impairments, namely, multi-layer coding (MLC) in the forward link, and open-loo...

Linear and nonlinear techniques for multibeam joint processing in satellite communications

Existing satellite communication standards such as DVB-S2, operate under highly-efficient adaptive coding and modulation schemes thus making significant progress in improving the spectral efficiencies of digital satellite broadcast systems. However, the constantly increasing demand for broadband and interactive satellite links emanates the need to apply novel interference mitigation techniques,...
