Abstract

Fractal characteristic of multipath fading signal is studied in the paper which shows that multifractal dimension is a key parameter for describing the signal propagation in wireless channels.The multifractal dimension and fractal parameter are calculated.Then a novel channel model is proposed and fractal interpolation is applied to reconstruct the signals.Simulation results show that the new model outperforms the conventional statistic models in both effectiveness and accuracy.
