Comparison between pi/4 DQPSK and Differential QFM in AWGN Channel

Wavelet modulation has the ability to send data simultaneously at multiple rates through a channel. In this paper, we present a performance analysis of fractal modulation transmission over additive, white, Gaussian noise (AWGN) channel. The novelty of this paper lies on the differentiall decoding which is accomplished using differentially coherent detection. We compared well known pi/4 DQPSK and new Differential Quadrature Fractal Modulation (DQFM).
