| Abstract: | Two blind source separation algorithms based on higher order statistics are studied. The performance is compared between these two algorithms and a algorithm based on second order statistics. To provide reference guideline for engineering applications, the computational complexity of three algorithms is studied. At last, the merits and shortcomings of three algorithms are summarized and the reason is discussed. |

| Keywords: | blind source separation higher order statistics second order statistics computational complexity |
