DOA Estimation Based on Sparse Signal Recovery Utilizing Double-Threshold Sigmoid Penalty
This paper proposes a new algorithm based on sparse signal recovery for estimating the direction of arrival (DOA) of multiple sources. The problem model we build is about the sample covariance matrix fitting by unknown source powers. We enhance the sparsity by the double-threshold sigmoid penalty fu...
