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 ...

Finding Direction in the Search for Selection [PDF]
Journal of Molecular Evolution, 2016 Tests for positive selection have mostly been developed to look for diversifying selection where change away from the current amino acid is often favorable. However, in many cases we are interested in directional selection where there is a shift toward specific amino acids, resulting in increased fitness in the species.

Dielectric Resonator Direction Finding Antenna
International Journal of Antennas and Propagation, 2011 The idea of using a cylindrical dielectric resonator antenna for mechanical direction finding and target tracking is presented. The hybrid feeding network of the receiving antenna comprised two ports: one for the broadside-type sum pattern and another ...

Finding communities in directed networks [PDF]
Physical Review E, 2010 To identify communities in directed networks, we propose a generalized form of modularity in directed networks by presenting the quantity LinkRank, which can be considered as the PageRank of links. This generalization is consistent with the original modularity in undirected networks and the modularity optimization methods developed for undirected ...
