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