Tight frequency reuse, e.g., beyond a 4-color scheme to increase a multi-beam satellite system’s capacity could make signal detection ‘interference-limited’, where conventional interference suppressing techniques would be ineffective, requiring rather some sophisticated/novel techniques, e.g., those exploiting interfering signals, to revive the overly degraded desired signals. The effectiveness of two such techniques was investigated and the results reported in this project.

This project represents the basis for enabling satellite systems using beam hopping capabilities. Beam hopping, based on the DVB-S2X transmission standard, enables time sharing of satellite capacity among different beams, making satellite systems more flexible and efficient. The satellite performs demultiplexing of the uplink signal and distribution via periodic switching of the satellite beam to different coverage areas. The switching time plan as well as the addressed coverage areas and coverage shapes can be reconfigured according to actual needs. In the context of such activity, a modulator, two terminals, as well as a beam-switching payload emulator are developed using the DVB-S2X Super-Framing Format 4 waveform.

This project investigates the possibility of providing an optical frequency converter based in integrated photonic circuit (PIC). In this project two main photonics platforms are investigated; Silicon photonics and Heterogeneous integration of InP-on-Silicon photonics. It comes in contrast that indeed integrated circuit provides more compact, energy deficient and low mass solution for the optical microwave applications.
Pilot Photonics has developed the world’s smallest and most versatile optical comb source based on photonic integration. Through PICSAL, its broad applicability to space applications including inter-satellite communication, fiber optic sensing, frequency generation, and frequency metrology is explored.
The challenge is that increasing throughput simply by increasing frequency reuse results in significant intra-system interference for co-channel beams in multi-beam satellite systems. The solution is to apply joint processing of the signals intended to the different beams at the gateway for interference management. This processing, precoding, ‘reverts’ the impact of the satellite RF channel and interferences.
This study analyses the requirements, constraints and trade-offs for a SatCom system for receiving multimedia services in a mobile, on-the-go (e.g. automotive) setting using Ka-band frequencies.

Results reach from technical answers like waveform design and end-to-end performance, over the quality of the experience for the user up to economic considerations like total cost of ownership and business cases.
The JAMES CCN3 project goal is the development of a RF test set-up using optical fibres as links between RF test bench and telecommunication payloads in AIT.
The first phase was dedicated to design the test set-up allowing gain stability improvement, to realize a representative breadboard and test it over temperature.
