A Switching Beamformer for Highly Non-Stationary Environments
Manan Mittal, Ryan M. Corey, John R. Buck +1
Adaptive beamforming is a cornerstone of array signal processing, yet its performance often collapses in the face of complex, rapidly changing interference. When interferers appear…
Time Segmented Beamforming via Dynamic Programming: Theory and Implementation
Manan Mittal, Ryan M. Corey, Diego Cuji +2
In dynamic acoustic environments with time-varying interferers, effective beamforming requires identifying stationary regions over time. The Capon beamformer, a whitened matched fi…
Adaptive Diagonal Loading using Krylov Subspaces for Robust Beamforming
Manan Mittal, Ryan M. Corey, John R. Buck +1
Reliable adaptive beamforming is critical for large microphone arrays operating in highly dynamic acoustic environments. In scenarios characterized by fast-moving talkers and inter…
Online Segmented Beamforming via Dynamic Programming
Manan Mittal, Ryan M. Corey, Diego Cuji +2
In dynamic acoustic environments characterized by time-varying interferers and moving sources, effective beamforming requires accurately identifying stationary regions over time. T…
Adaptive Diagonal Loading for Norm Constrained Beamforming
Manan Mittal, Ryan M. Corey, John R. Buck +1
Reliable adaptive beamforming is critical for large microphone arrays operating in highly dynamic acoustic environments. In scenarios characterized by fast-moving talkers and inter…
Adaptive Linearly Constrained Minimum Variance Framework for Volumetric Active Noise Control
Manan Mittal, Ryan M. Corey, Andrew C. Singer
Traditional volumetric noise control typically relies on multipoint error minimization to suppress sound energy across a region, but offers limited flexibility in shaping spatial r…
