A Novel Reconfigurable Vector-Processed Interleaving Algorithm for a DVB-RCS2 Turbo Encoder [PDF]

open access: yesCoRR, 2023
Turbo-Codes (TC) are a family of convolutional codes enabling Forward-Error-Correction (FEC) while approaching the theoretical limit of channel capacity predicted by Shannons theorem. One of the bottlenecks of a Turbo Encoder (TE) lies in the non-uniform interleaving stage.

Frequency Packing and Multiuser Detection for CPMs: How to Improve the Spectral Efficiency of DVB-RCS2 Systems [PDF]

open access: yesIEEE Wireless Communications Letters, 2013
We consider a frequency division multiplexed system where each user adopts a continuous phase modulation (CPM) and multiuser detection is employed at the receiver side. The spectral efficiency (SE) is used as a performance measure to compare, from an information-theoretic point of view, different modulation formats.

A new RA-DA hybrid MAC approach for DVB-RCS2

open access: yes2015 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2015
This paper proposes a new MAC scheme for DVB-RCS2 aimed to efficiently address M2M/SCADA traffic. The proposed scheme relies on the idea to complement Random Access (RA) schemes with Dedicated Access (DA) schemes, when traffic spikes feed the network.

Dynamic uplink frame optimization with ACM in DVB-RCS2 satellite networks

open access: yes2012 IEEE First AESS European Conference on Satellite Telecommunications (ESTEL), 2012
In current generation of satellite networks, modulation and coding schemes can be dynamically changed in real-time to face different link conditions. Therefore, the link budget is no more required to be computed under the worst-case, with relevant advantages in terms of efficiency.

Implementation of a geographical routing scheme for low Earth orbiting satellite constellations using intersatellite links

open access: yesInternational Journal of Satellite Communications and Networking, Volume 39, Issue 1, Page 92-107, January/February 2021., 2021
A geographical routing scheme for LEO satellite constellations with intersatellite links is proposed, implemented, and analyzed for two Walker Star constellations. The approach targets reliable transmissions with low latency and high data rates even in scenarios with significant traffic load.
