Graph Signal Processing: Overview, Challenges and Applications
Proceedings of the IEEE, 2018 Research in Graph Signal Processing (GSP) aims to develop tools for processing data defined on irregular graph domains. In this paper we first provide an overview of core ideas in GSP and their connection to conventional digital signal processing.

Residual feedback suppression with extended model-based postfilters
EURASIP Journal on Audio, Speech, and Music Processing, 2021 When designing closed-loop electro-acoustic systems, which can commonly be found in hearing aids or public address systems, the most challenging task is canceling and/or suppressing the feedback caused by the acoustic coupling of the transducers of such ...

An Information-Theoretic Approach to the Chipless RFID Tag Identification
IEEE Access, 2019 In this paper, we focus on the chipless radio-frequency identification (RFID), where the tag information bits are encoded by the peak/notch pattern appeared in the frequency spectrum of the radar cross section (RCS) of the tag. In particular, we restrict
