Forward Adaptation of Novel Semilogarithmic Quantizer and Lossless Coder for Speech Signals Compression
In this paper new semilogarithmic quantizer for Laplacian distribution is presented. It is simpler than classic A-law semilogarithmic quantizer since it has unit gain around zero. ...

A Zador-like formula for quantizers based on periodic tilings
We consider Zador's asymptotic formula for the distortion-rate function for a variable-rate vector quantizer in the high-rate case. This formula involves the differential ent...

Asymmetric multiple description lattice vector quantizers
We consider the design of asymmetric multiple description lattice quantizers that cover the entire spectrum of the distortion profile, ranging from symmetric or balanced to success...

Quantizer design and distributed encoding algorithm for source localization in sensor networks
— In this paper, we propose a quantizer design algorithm that is optimized for source localization in sensor networks. For this application, the goal is to minimize the amount of...
