Abstract

A novel blind source separation method was proposed based on array average in the fractional Fourier domain, which introduces a set of weighting function into the fractional Fourier domain to de?crease the noise level and interaction among the source signals. Compared with the traditional blind source separation method, the proposed method does not require whitening and joint-diagonalization to the hybrid matrix, has lower complexity, small amount of operation and good anti-jamming capability.

Key words
