摘　　要：本文研究接收信号维数大于源信号维数的盲分离,提出了一种基于广义特征函数的信号盲分离新方法,该方法提高了信号分离的精度,减少了计算量。文中就方法进行了理论推导,并给出了计算机仿真结果,仿真结果表明理论分析是正确的。Blind source separation (BSS) where the dimension of receiving signal is higher than that of source signal is discussed, accordingly a new algorithm for blind source separation (BSS) based on the generalized characteristic function is proposed. The accuracy for signal separation using the new algorithm is improved, and the computation complexity is reduced. Formulas out of the proposed algorithm are derived and computer simulation results are also given to verify the theoretical analysis.
