This paper applies chaos and fractal theories to the analysis of mulitpath fading in mobile radio communications for the first time

and investigates its nonlinear dynamical system characteristics based on the measured data from field trials.By reconstructing the status space and correlation dimension

we show that the dynamical system of the multipath fading channels has finite degree of freedom and a positive maximum Lyapunov exponent.The chaotic characteristic of the multipath fading is demonstrated and the nonlinear evolution mechanism is observed.Finally

we apply fractal model to the interpolation of multipath signals

yielding reasonably accurate replications.The results indicate that the nonlinear dynamical system could be a more suitable model than the conventional random process for describing multipath fading phenomenon.
