Probability of Resolution of Partially Relaxed Deterministic Maximum Likelihood: An Asymptotic Approach

The Partial Relaxation approach has recently been proposed for high resolution Direction-of-Arrival estimation (see Trinh-Hoang null et al. , IEEE Trans. Signal Process., 2018; Trinh-Hoang null et al. , ICASSP, 2018). In this article, we investigate the outlier production mechanism of the Partially Relaxed Deterministic Maximum Likelihood (PR-DML) Direction-of-Arrival estimator using tools from Random Matrix Theory. Instead of applying a single...
