Worst-Case and Covariance-Reconstruction Robust Adaptive Beamforming: Equivalence and Closed-Form Solution
Licheng Zhao, Rui Zhou, Wenqiang Pu +1
Robust adaptive beamforming (RAB) has developed along two separate lines. The worst-case-constrained approach guards against steering vector mismatch with a bounded uncertainty set…

An Efficient and Globally Optimal Algorithm for Nonconvex QCQP with One Equality Constraint
Licheng Zhao, Rui Zhou, Wenqiang Pu
In this paper, we concentrate on a particular category of quadratically constrained quadratic programming (QCQP): nonconvex QCQP with one equality constraint. This type of QCQP pro…
