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…
Improved Design Method for Nearly Linear-Phase IIR Filters Using Constrained Optimization
R. C. Nongpiur, D. J. Shpak, A. Antoniou
A new optimization method for the design of nearly linear-phase IIR digital filters that satisfy prescribed specifications is proposed. The group-delay deviation is minimized under…
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…
Improved Robust Node Position Estimation in Wireless Sensor Networks
R. C. Nongpiur
A new method for estimating the relative positions of location-unaware nodes from the location-aware nodes and the received signal strength (RSS) between the nodes, in a wireless s…
