Model-Based Learning for DOA Estimation with One-Bit Single-Snapshot Sparse Arrays
Yunqiao Hu, Shunqiao Sun, Yimin D. Zhang
We address the challenging problem of estimating the directions-of-arrival (DOAs) of multiple off-grid signals using a single snapshot of one-bit quantized measurements. Convention…

Enhancing Off-Grid One-Bit DOA Estimation with Learning-Based Sparse Bayesian Approach for Non-Uniform Sparse Array
Yunqiao Hu, Shunqiao Sun, Yimin D. Zhang
This paper tackles the challenge of one-bit off-grid direction of arrival (DOA) estimation in a single snapshot scenario based on a learning-based Bayesian approach. Firstly, we fo…
