Design and analysis of a DPCM system with a switched quantizer

Abstract

Theoretical analysis of matched differential pulse code modulation (DPCM) of a first-order Gauss-Markov process has been done for a DPCM system with a uniform quantizer, an entropy constrained optimal uniform-threshold quantizer, and an adaptive step-size uniform quantizer. We design and analyze a DPCM system with a Lloyd-Max quantizer and a DPCM system with a switched quantizer (composed of a bank of Lloyd-Max quantizers and a switching rule; a a quantizer is chosen from this quantizer bank according to the switching rule) for a first-order Gauss-Markov process.<>
