A typical approach to eliminate impulse noise is to use the ℓ 1-norm for both the data fidelity term and the regularization terms. However, the ℓ 1-norm tends to over penalize signal …
Direction of arrival (DOA) estimation is an essential and fundamental part of array signal processing, which has been widely used in radio monitoring, autonomous driving of …
