摘要：
The blind signal separation (BSS) algorithm obtains each original/source signal from the observed signal collected by the receiving antenna or sensor. Objective/loss/cost function and optimization method are two key parts of BSS algorithm. Modifying the objective function and optimization from the perspective of neural network (NN) is a novel concept in BSS domain.
$$L_2$$
regularization is adopted as a term of maximum likelihood estimation (MLE)-based objective function like in Liu et al.(Sensors 21(3):973, 2021); however, we modifi...
