The "International Workshop on Smart Antennas" (WSA) is a prominent annual forum for presenting the latest research on smart antennas and related theoretical and technical aspects in modern wireless communication systems. The workshop series, which began in 1996, aims to continue and accelerate momentum in the field.
The 28th edition of WSA was hosted by the Friedrich-Alexander-Universität Erlangen-Nürnberg in Erlangen, Germany from September 16–18, 2025.
Optimal Azimuth Sampling and Interpolation for Bistatic ISAC Setups
The INUE in collaboration with Nokia presented the paper "Optimal Azimuth Sampling and Interpolation for Bistatic ISAC Setups", authored by Alexander Felix, Silvio Mandelli, Marcus Henninger, and Prof. Stephan ten Brink, that determines the optimal way for the transmitter and receiver to sample the environment's angular domain in a bistatic ISAC system.
This research extends prior work on monostatic systems to the equally important bistatic setups, a key configuration for future ISAC cellular scenarios. The separation of the azimuth operations of the arrays allows for optimal sampling and interpolation based on DFT theory per array, using a normalized angular frequency (NAF). This strategy, validated by Monte Carlo experiments, enables lossless reconstruction of the angular domain, providing a significantly more efficient and accurate sampling and interpolation technique compared to legacy methods. Consequently, this strategy paves the way for advanced bistatic ISAC deployments.
For their work, the INUE and Nokia researchers received the WSA 2025 Best Paper Award.
