Abstract

We propose a novel mixed analog-to-digital converter (ADC) architecture for direction-of-arrival (DOA) estimation using a uniform linear array, where the in-phase and quadrature-phase channels can be independently sampled by different ADCs. We derive the Cramér-Rao bound (CRB) and utilize its lower bound to optimize the placement of different ADCs via a swap-based method. Numerical examples are provided to demonstrate the superiority of the optimized placement of different ADCs over existing schemes. © 2024 IEEE.
