On the Effect of Random Snapshot Timing Jitter on the Covariance Matrix for JADE Estimation

This paper analyzes how random snapshot timing jitter perturbs the sample covariance matrix used in joint angle and delay estimation (JADE). Closed-form expressions are derived for the perturbation, and the resulting accuracy loss in downstream JADE estimators is quantified, informing acquisition-system design choices.
