Abstract
Comparative analysis of the threshold SNR and/or sample support values where genuine maximum likelihood DOA estimation starts to produce "outliers" is conducted for unconditional (stochastic) and conditional (deterministic) problem formulations. Theoretical predictions based on recent results from Random Matrix Theory (RMT) are provided and sup ported by simulation results.
