An Effective Sources Enumeration Approach for Single Channel Signal at Low SNR

In order to address the problem of achieving the poor performance of a single-channel receiver operated at a low signal-to-noise ratio (SNR) based on the existing source number estimation method, an effective source enumeration approach for the single-channel receiver operated at a low SNR is proposed in this paper. The proposed method is based on the empirical mode decomposition (EMD) with the auto-correlation coefficient matrix (ACCM) and the...
