The purpose of this activity is to study, analyse and simulate new advanced techniques at physical and upper layers (these latter only to support the new devised physical layer techniques) for the forward and return link of future satellite networks, targeting the consumer and professional fixed and mobile terminal market. The goal is to increase the spectral and energy efficiency of the currently used solutions, enable higher data rates for the same link availability, with the end result of increasing the overall competitiveness of the satellite networks. The performance of such techniques shall be thoroughly investigated by means of analysis and computer simulations and their benefits at system level also estimated together with their expected complexity.
RG1 has investigated the following techniques:
RG2 has investigated the following techniques:
Pre-coding with “user-clustering” was selected as the most promising technology at the end of Task 1, detailed investigation was carried out in Tasks 2 and 3 for the physical layer (in particular synchronisation matters) and system level aspects respectively.
Based on the achieved or expected performance improvements, the results of the study will be used to define a roadmap within the ARTES program for the development (including validation) of the corresponding technologies and products.
Many contributions to DVB-S2X standardisation were also realised.
The consortium is organised into two Research Groups (RG) which will carry out parallel investigations during the first phase of the project, namely:
After selecting the most promising technology or subset of technologies, University of Bologna will carry out the detailed physical layer assessment in Task 2 and DLR the system level assessment in Task 3.
Task 1: Investigation of the Air Interface Enhancements (completed)
Task 2: Definition and Assessment of the New Air Interface (completed)
Task 3: System Performance Assessment and Technology
The project was kicked off on 2012, December 1st. The final review and presentation took place on 2015, March 5th.
