OPTIMIZATION OF NON-ADAPTIVE DIFFERENTIAL PCM SYSTEMS FOR MARKOV-1 SIGNALS,

Abstract

The response of a non-adaptive differential pulse code modulation system to a first order Markov input signal is investigated through computer simulation techniques, and an attempt is made to optimize both the predictor and quantizer with respect to that signal. The criteria used are signal-to-quantizing noise ratio and entropy of the transmitted signal. Channel noise is not considered. Both uniform and nonuniform quantization are examined, but only linear prediction is used. The sequence of Markov-1 input samples is generated by passing uncorrelated Gaussian variables, which are created by a random number generator, through a simulated digital filter. (Author)
