Multiplexed and distributed radio receiver systems, such as for robust GNSS reception where interfering jammers and spoofers are suppressed, and for radio astronomy phased arrays, are increasingly being subjected to higher demands. This is related to the more intensive use of the radio spectrum, the necessity to make systems more sensitive and broader in bandwidth, while simultaneously limiting energy consumption.
The goal of this project is to determine the properties of a state-of-the-art distributed radio receiver system. Based on a selection of electronic components, various architectures are compared based on system behaviour, such as achievable linearity, noise (system sensitivity), synchronisation accuracy, energy consumption, and ITAR restrictions. The knowledge gained from this will be fed back to the HTSM microelectronics community in the form of component and architecture recommendations.
