ZIV-Zakai Bound for DOA Estimation with Gain-Phase Error

Sihan Wen, Zongyu Zhang, Chengwei Zhou, Zhiguo Shi

ICASSP 2024accepted

Compared with the commonly used Cramér-Rao bound, the Ziv-Zakai bound (ZZB) is a global tight lower bound for evaluating the performance of parameter estimators. However, the existing ZZB for multi-source direction-of-arrival (DOA) estimation is derived under an ideal array assumption, where the gai…

Explicit Ziv-Zakai Bound For Multiple Sources Doa Estimation

Zongyu Zhang, Yujie Gu, Zhiguo Shi

ICASSP 2023accepted

In direction-of-arrival (DOA) estimation, Cramér-Rao bound is widely used to lower bound the mean square error (MSE), which, however, is a local bound. As a global bound, existing Ziv-Zakai bound (ZZB) is restricted by the single source assumption and has not considered the effect of ordering proces…
