摘要

对具有均匀量化器、熵约束最优均匀阈值量化器和自适应步长均匀量化器的一阶匹配差分脉冲编码调制(DPCM)系统进行了理论分析。我们设计并分析了一个带有Lloyd-Max量化器的DPCM系统和一个带有切换量化器的DPCM系统(由一组Lloyd-Max量化器和一个切换规则组成);对于一阶高斯-马尔可夫过程,根据切换规则从该量化器组中选择量化器。

Design and analysis of a DPCM system with a switched quantizer
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.<>
