In this paper the modeling of a signal by a chaotic generator with respect to a specified signal statistic will be considered. To accomplish that, the considered class of n-dimensional piecewise linear Markov generators will first be analyzed analytically, yielding an algebraic expression for the statistical quantity in question. Based on this analytical(More)
| For chaos communication schemes, one chooses typically a particular demodulation principle , which is then evaluated in terms of bit error rate for a given channel. In this approach we start from the maximum likelihood decision criteria and derive an optimal estimator for initial conditions. We assume that the information to be transmitted is coded in the(More)
In classical speech synthesis linear systems are used to achieve the required spectral properties 1]. Figure 1 shows a simpliied discrete-time model of speech synthesis which is used e.g. in Linear Predictive Coding (LPC). It contains two signal sources (a pulse train generator for voiced speech and a white noise generator for unvoiced speech), an ampliier(More)
