Abstract
A method, a system and an intelligent terminal for one-bit quantization DoA estimation, which include: when a quantity of far-field and uncorrelated spatial narrow-band source signals are incident from different directions to a uniform linear array receiver, receiving the narrow-band source signals by a quantity of antenna array elements, and the vector and matrix are used to model the received signals by one-bit quantization to obtain a joint probability mass model of one-bit quantization DoA estimation; deriving the joint probability mass model of one-bit quantization DoA estimation, and constructing an lnorm optimization model based on the maximum likelihood principle; solving the steepest descent direction of the optimization model by steepest descent method to obtain the one-bit quantization DoA and the source number.
