%X By theory analysis, a new method based on pseudo extraction vectors was put forward for accomplishing underdetermined blind signal separation (UBSS) in the paper. The method accomplishes UI3SS by judging which signal dominating for each sampling and choosing corresponding pseudo extraction vector for it to recover sampling data of source signals. Some conclusions can be seen by separately simulating the method based on pseudo extraction vectors and linear programming; the method based on pseudo extraction vectors free of optimizing process increases the velocity of separating source signals. The velocity of separating of the method based on pseudo extraction vectors is tens of times of the method basal on linear programming.
