Abstract

This work generalizes the chaotic map recently introduced by the authors with the addition of two new contro l parameters. The Lyapunov exponent is employed to analyze th e chaotic dynamics of the proposed map. The spectral characte ris- tics of chaotic signals generated by this map as a function of the control parameters are also investigated. The proposed map can be used in symbolic dynamics based communication systems wi th advantages over current approaches based on piecewise line ar maps.
