RF signal processing
Conditioning, channelisation and analysis of acquired radio signals.
Research & development
Research that is expected to reach hardware
R&D is organised around signal-processing and radio problems that can be simulated, implemented on FPGA or SDR, and checked against a measurement.
Focus areas
Current research attention
Multi-channel synchronization
Keeping receivers aligned in time and phase.
Direction finding
Phase- and amplitude-aware angle estimation, including calibration.
TDOA localization
Delay estimation, GCC-PHAT and multilateration studies.
FPGA acceleration
Moving correlation, transforms and filtering onto deterministic fabric.
SDR architectures
Programmable radio structures for experiments and early prototypes.
Digital communications
Waveform-aware processing where the signal structure is known or partly known.
Detection & estimation
Algorithms for deciding that a signal is present and estimating its parameters.
