Analysis of Support Region for Laplacian Source's Scalar Quantizers

Abstract

The goal of this paper is to find the estimation of the support region of optimal scalar quantizers for Laplacian input signals with unrestricted amplitude range in terms of the number of quantization levels. The companding concept has been used because of its usefulness in analyzing and optimizing nonuniform quantizers with large number of levels. The support is shown to grow logarithmically with the number of quantization levels
