摘　　要：Based on the minimum-range approach, a new geometric approach is proposed to deal with blind source separation in this paper. The new approach is the batch mode of the original minimum-range approach. Compared with the original approach, the optimization algorithm of the proposed approach needs no parameters and is more efficient and reliable. In addition, the extension of minimum-range- based approaches is discussed. The simulations show the efficiency of the proposed approach.@2009 National Natural Science Foundation of China and Chinese Academy of Sciences.
