Direction Finding Using Compressive One-Bit Measurements
IEEE Access, 2018 In this paper, we propose a novel direction-of-arrival (DOA) estimation scheme, which is named the compressive one-bit measurement scheme. In the proposed scheme, the one-bit quantization technique is used to reduce the system cost in terms of the analog-

Deep learning-based direction finding in the presence of direction-dependent mutual coupling
ICT Express, 2023 In this paper, the problem of direction finding is considered for millimeter-wave communication with direction-dependent mutual coupling. For direction-of-arrival estimation, a low-complexity deep neural network (DNN)-based regression model is proposed ...

Optimal estimation of quantum dynamics [PDF]
, 2000 We construct the optimal strategy for the estimation of an unknown unitary transformation $U\in SU(d)$. This includes, in addition to a convenient measurement on a probe system, finding which is the best initial state on which $U$ is to act.
