ESTIMATION OF THE SUPPORT REGION FOR LAPLACIAN SOURCE SCALAR QUANTIZERS

Zoran Peric - Jelena Nikolic - Dragoljub Pokrajac

   The goal of this paper is finding an asymptotic equation which determines the amplitude range of asymptotically optimal scalar quantizers for Laplacian input signals with an unrestricted amplitude range. It is very important to show how the amplitude range depends on the number of quantization levels. The approximation method for determining the amplitude range is suggested. This method can be used for simple and fast estimation of the amplitude range for scalar quantizer, as a result the quantizer is ideally loaded.

Keywords: Laplacian source, scalar quantizer, support region.
