A single-channel source number estimation method is presented. The single-channel received signal is firstly decomposed into several intrinsic-mode functions (IMFs) by empirical mode decomposition (EMD). Then the information theoretic criteria (ITC) based methods, MDL and AIC, are introduced to realize the source number estimation. And the diagonal loading technique is used to smooth the fluctuation of the eigenvalues. Compare with the previous works, the proposed method can effectively improve the source number detection performance.
