High throughput highly re-configurable bent-pipe processor for access networks<br />
The proposed activity aims at the design, implementation and validation of the Proof of Concept (PoC) of a high throughput<br />
highly re-configurable and scalable digital processor for future bent-pipe satellite broadband access networks that meets these<br />
new challenging requirements in terms of flexibility and processed bandwidth (expected to be up to 50 GHz). The prototype<br />
shall demonstrate all the key functionalities of the processor (e.g. high bandwidth signal processing algorithms, channel to<br />
beam allocation flexibility, wideband digital beam forming, etc.) and assess in detail the use of cutting-edge digital<br />
technologies (e.g. 0.13 micro-m, new low power consumption ADC/DAC) needed for achieving efficient processing of the<br />
large bandwidths involved within the next generation of communication systems. For budgetary reasons the PoC will make<br />
extensive use of FPGA technology. The prototype shall be implemented at a laboratory breadboard level and is expected to<br />
work at re<strong>du</strong>ced scale in terms of processed bandwidth per beam and be scaled-down in terms implemented links. The PoC<br />
shall allow a thoroughly validation of the proposed architecture, signal processing algorithms and achievement of the<br />
performance requirements. Power and mass estimate for the final target technology shall be however performed. A real-time<br />
air interface simulator shall be developed for both up and downlink in order to provide the processor with the required IF and<br />
control signals. The simulator shall cover functions such as interference and propagation effects, satellite delays, network<br />
synchronization mechanisms, payload impairments, packet demo<strong>du</strong>lation, background signalling loading of the switch<br />
controller, etc.<br />

Title:<br />
New concepts for <strong>du</strong>al-gridded reflectors (study)<br />
Dual-gridded reflector antennas allow the combination of two apertures in almost the same room that would be occupied by<br />
only one normal reflector. This is achieved by using polarisation sensitive grids printed on the reflector surfaces. This concept<br />
is extremely important <strong>du</strong>e to the accommodation constraints of the platforms and lead to very high polarisation purity.<br />
Ku-band <strong>du</strong>al-gridded reflectors are widely used today on commercial satellites. This activity deals with the study of possible<br />
technological implementations of <strong>du</strong>al-gridded reflectors for telecommunications applications in Ka-band. New concept and<br />
materials are mandatory <strong>du</strong>e to high transmission losses of the front shell (approximately 0.8 dB) when Ku-band technology is<br />
considered for Ka-band. It is proposed to follow this preliminary design activity by an ARTES-funded demonstration phase.<br />
Deliverables:<br />
Design of <strong>du</strong>al-gridded reflector antenna at Ka-band. RF and mechanical samples to be used as proof of concept.<br />
