Semi-Transparent Packet Switching by Satellite: Migrating Existing Technologies for New Opportunities

Energy efficient CPM waveforms for satellite mesh networks

“…CPM waveforms in the DVB-RCS2 standard are designed with a rate-1/2 convolutional code, possibly punctured to achieve a desired code rate, identified by generator polynomials [5,7] in the case of constraint length K = 3 and [15,17] in the case of constraint length K = 4, which are reported in [7] and [8] as the optimal codes in the sense of the minimum Hamming distance (d min ). When designing the new binary (M = 2) CPM waveforms in power-limited environments, thus for lower operating spectral efficiencies (⌘ = 0.25 bit/s/Hz) the same criterion, based on the minimum Hamming distance, has been originally followed in order to select the most suitable rate-1/4 code.…”

Performance analysis of a mesh satellite system based on linear and continuous phase modulations

“…1. A semi-regenerative satellite segment is considered [5]- [6]- [7], in order to achieve full-mesh connectivity of multiple terminals without the need of onground Hub stations.…”

“…The use of regenerative payload has been addressed in [4], while semi regenerative payloads have been considered in [5], [6], [7]. In [8] different architectures for mesh satellite networking have been designed providing link budgets and setting up the framework for a detailed analysis of the waveforms performance in mesh systems reported in this paper.…”

“…In [8] different architectures for mesh satellite networking have been designed providing link budgets and setting up the framework for a detailed analysis of the waveforms performance in mesh systems reported in this paper. More in detail, reference [8] provides the key elements of the mesh satellite network, which has been designed considering case specific optimizations as well as input from previous studies [2]- [7]. In this paper we move from the system view to the link view, focusing on link-level aspects and impairments.…”
