Characterization of Mems Microphone Sensitivity and Phase Distributions with Applications in Array Processing

ICASSP 2021accepted

An array with MEMS microphones can distinguish individual noise sources in an environment through spatial filtering. Its effectiveness depends on the variations in microphone sensitivity and phase. Quantification of these variations is valuable, because it enables assessment and optimization of arra…

Approximate Inference by Kullback-Leibler Tensor Belief Propagation

ICASSP 2020accepted

Probabilistic programming provides a structured approach to signal processing algorithm design. The design task is formulated as a generative model, and the algorithm is derived through automatic inference. Efficient inference is a major challenge; e.g., the Shafer-Shenoy algorithm (SS) performs bad…

Robust Bayesian Beamforming for Sources at Different Distances with Applications in Urban Monitoring

ICASSP 2019accepted

Acoustic smart sensor networks can provide valuable actionable intelligence to authorities for managing safety in the urban environment. A spatial filter (beamformer) for localization and separation of acoustic sources is a key component of such a network. However, classical methods such as delay-an…
