针对单通道的源数盲估计技术,提出了一种基于经验模态分解和交叉验证技术相结合的源数估计方法,该方法首先通过经验模态分解技术将单通道的观测信号转换为虚拟的多通道观测信号,然后采用基于交叉验证技术来确定混合在单通道中的源信号个数.仿真实验结果表明:该方法能准确地估计出混合在单通道中服从超高斯分布、亚高斯和高斯分布的源信号个数

A method based on empirical mode decomposition and cross validation presented for the blind source numbers estimation under single-channel case,in which empirical mode decomposition used to change observation signals of single-channel into observation signals of multi-dimension channel,then the source numbers estimated according to the principle of cross validation.The simulation results show the proposed method can estimate numbers of those source signals of Gaussian,super- and sub-Gaussian distribution which are mixed into single-channel
