Estimation of Source Number for Single-Channel Received Signal

Estimation of Source Number for Single-Channel Received Signal

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 real...
