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.
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.
