On Ground Beam Forming and Multi User Detection Proof of Concept

In the frame of the on-going ARTES-5.1 ESA project “On Ground Beam Forming Networks And Multi User Detection Proof Of Concept” different scenarios of interest for the OGBF with Multi user detection technique has been defined, based on a single S-Band GEO satellite. This paper is focused on the definition and design of a hardware test bed implementing a scaled version of an OGBF/MUD system in order to verify the achievable performance. The OGBF demonstrator test bed includes a traffic emulator with relevant channel impairments, a satellite emulator including frequency conversion and multiplexing of the feeds signals and HPA emulation, and a gateway emulator with on ground frequency conversion, digital demultiplexing and MMSE-SIC based Multi user detector.
