摘    要:提出了一种基于边检测的盲源分离几何算法,该算法只需要检测到观测信号X的所有独立的边,然后根据数字信号混叠时的几何性质,分离出源信号,首先给出了问题的数学模型,然后对其分析并给出具体的分离算法,最后给出了仿真结果.仿真结果表明:该算法比一般的几何算法复杂度降低了,分离时间减少了,并且能保证分离效果.

关 键 词:盲源分离  天线阵列  m维超平行体  无线通信

Abstract:In this paper, the problem of blind estimating multiple digital co-channel communication signals using an antenna array is discussed. A new approach is proposed to find all the independent edges of X based on an analysis of the x projections onto the coordinates. Through the simulation results of separating two blind audio signals, it is easily seen that the blind signals could be quickly and rightly separated with the proposed algorithm.
Keywords:source separation  m-dimensional parallelotope  antenna array  wireless communication
