N2 - This paper investigates the wideband direction-ofarrival (DOA) estimation problem using one-bit analog-to-digital converters (ADCs). Under the majorization-minimization (MM) framework, pre-quantization data reconstruction is achieved through maximum likelihood estimation, followed by frequency decomposition based on the recovered data to obtain subband signals. The step of pre-quantization data recovery effectively mitigates spectrum distortion induced by one-bit quantization. Then in the second step, a joint weighting wideband generalized sparse iterative covariance estimation method is proposed, achieving improved performance by processing shared information across multiple subbands of interest simultaneously. Simulation results are provided to demonstrate the effectiveness of the proposed two-step one-bit wideband DOA estimation method.
