An Asymptotically Efficient Weighted Least Squares Estimator for Co-Array-Based DoA Estimation

Co-array-based Direction of Arrival (DoA) estimation using Sparse Linear Arrays (SLAs) has recently gained considerable interest in array processing thanks to its capability of providing enhanced degrees of freedom. Although the literature presents a variety of estimators in this context, none of th...
