Multifractal signal processing is now receiving increasing attentions. However, relevant researches mainly focus on differentiability and dimension of the fractal subset, such as fractal dimension and multifractal spectrum, or fractal and multifractal analysis in the fractional domain. In this paper, we propose a fractional domain singularity power spectrum (FDSPS) based on singularity power spectrum (SPS) and fractional order Fourier transform (FrFT). Due to the advantages of FrFT, including fractal fidelity, energy aggregation and signal separation in the fractional domain, the FDSPS can effectively represent the signal power distribution along with singularity exponent in the fractional domain. The discrete approximation algorithm of FDSPS is introduced. Simulation results indicate that fractional domain SPS can reveal effectively FrFT domain singular power distribution of fractal signal and provide application prospect of multifractal signal analysis processing.
