Message Passing Based Block Sparse Signal Recovery for DOA Estimation Using Large Arrays
Yiwen Mao, Dawei Gao, Qinghua Guo +1
This work deals with directional of arrival (DOA) estimation with a large antenna array. We first develop a novel signal model with a sparse system transfer matrix using an inverse…
