SINGLE CHANNEL FULL DUPLEX TECHNIQUES FOR SATELLITE COMMUNICATIONS (ARTES FPE 1B.133) - EXPRO+

Description

The objective of the activity is to assess the feasibility of applying single channel full duplex techniques within satellite communication networks. Simultaneously transmitting and receiving information in a single frequency channel has already proven a viable approach in other wireless communication application domains and has the potential to double total system throughput. Such systems typically employ a combination of both analogue and digital Signal Interference Cancellation (SIC) techniques to achieve the necessaryisolation between transmit and receive signals, and such techniques have therefore advanced rapidly over the last few years. The study should include a survey of the current state of the art for SIC techniques and associated technology, an evaluation of the suitability of commonly used full duplex air interfaces to satcom scenarios (identifying any required adaptions), as well as identifying and developing bespoke solutions. The activity should evaluate operations within all frequency bands currently used for satellite communication, i.e., from VHF to mm-wave frequencies, and seek to identify the most promising use cases and application domains, e.g.,backhauling, feeder and user links, ISLs, etc. In addition, the impact on satellite payload design should be identified as well as any radio regulatory implications.
