Maximizing the Signal-to-Alias Ratio in Non-Uniform Filter Banks for Acoustic Echo Cancellation
R. C. Nongpiur, D. J. Shpak
A new method for designing non-uniform filter-banks for acoustic echo cancellation is proposed. In the method, the analysis prototype filter design is framed as a convex optimizati…

L-infinity Norm Design of Linear-phase Robust Broadband Beamformers using Constrained Optimization
R. C. Nongpiur, D. J. Shpak
A new method for the design of linear-phase robust far-field broadband beamformers using constrained optimization is proposed. In the method, the maximum passband ripple and minimu…
