A Method of Blind Source Numbers Estimation of Single-channel
Haifeng Zhou · Journal of Jimei University · 2012
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.
