Multiwavelet-based Fractal Modulation

Z. Zhang and J. Ilow (Canada)



This paper introduces a fractal modulation scheme which is a vector version of the conventional fractal modulation [1]. The new scheme has all the advantages of its scalar prototype but achieves a higher bandwidth utilization. Using multiwavelets, the proposed signaling scheme is constructed by extending the conventional fractal modulation from the scalar to the vector mode of operation. Performance of the new modulation scheme with the orthogonal scaling function pair is estimated and simulated in Additive White Gaussian Noise (AWGN) and flat slow Rayleigh fading channels. Good agreements between theoretical and simulated results are obtained.
