Hongyuan Gao, Ziyi Du, Zhao Shen, Vantoi Vu · 2023
To deal with the direction of arrival (DOA) estimation of wideband signals under impulse noise, this paper proposes a weighted signal subspace fitting estimation method based on focusing composite entropy, and designs a continuous quantum coot search mechanism to efficiently solve the wideband direction-finding equation. These simulation experimental results show that the quantum coot optimization algorithm (QCOA) has a good suppression effect on pulse noise and has excellent decoherence ability. At the same time, it has significant improvement in estimation performance compared to other existing algorithms.
