Abstract
Aiming at the problem of satellite communication signal and jamming blind separation in noisy environment, a new algorithm for convolutive mixture blind source separation (BSS) by exploiting the householder transformation to realize the joint diagonalization of high-order cumulant and operation in the frequency domain was proposed. Compared with the classical methods, simulation results show that the proposed algorithm has lower computational complexity and better separation performance. When signal to noise ratio (SNR) is greater than lOdB, the novel algorithm of anti-jamming can realize the separation of communication signals and the jamming, and has good separation performance.关键词
