Optimal Mixed-ADC Arrangement for DOA Estimation Via CRB Using ULA

ICASSP 2023accepted

We consider a mixed analog-to-digital converter (ADC) based architecture for direction of arrival (DOA) estimation using a uniform linear array (ULA). We derive the Cramér-Rao bound (CRB) of the DOA under the optimal time-varying threshold, and find that the asymptotic CRB is related to the arrangem…
