enhancing DOA estimation in mixed-resolution array cases. Concurrently, DOA estimation, supported by graph signal processing, introduces innovative methodologies for discerning arrival directions ...

Adaptive filtering is a type of signal processing that adjusts the filter parameters dynamically based on the input and output signals, or some other criteria. This allows the filter to adapt to ...

Abstract: This work presents a new approach, based on Graph Signal Processing, to estimate the direction of arrival (DoA) of an incoming narrowband signal hitting on an array of sensors. By building ...

Six recent developments are also provided at the end to indicate possible promising directions for future SAM research, which are graph signal processing (GSP) for sensor networks; tensor-based array ...
