A New Sparse Linear Array With Three-Level Nested Structure [PDF]
, 2019 Mutual coupling, which is caused by a tight intersensor spacing in uniform linear arrays (ULAs), will, to a certain extent, affect the estimation result for source localisation. To address the problem, sparse arrays such as coprime array and nested array

2D DOA Estimation Exploiting Vertical Synthetic Planar Arrays
IEEE Access, 2021 In this paper, vertical motions of sparse linear arrays (SLAs) are utilized to generate equivalent synthetic planar arrays for two-dimensional (2D) direction-of-arrival (DOA) estimation.

Evaluating Spatial Resolution and Channel Capacity of Sparse Cylindrical Arrays for Massive MIMO
IEEE Access, 2017 How to design antenna arrays plays an important role in wireless communications, especially when there are hundreds of antennas. In massive multiple-input and multiple-output (MIMO), if the number of antennas and RF chains are increasing, the channel ...

IET Radar, Sonar & Navigation, 2022 As we all know, the non‐uniform array is widely used in the mixed near‐field (NF) and far‐field sources localization. The nested array contains a uniform linear array, it is easy to be affected by mutual coupling, so we propose a symmetric thinned ...

, 2016 Orthogonal Arrays allow us to test various levels of each factor and balance the different factors so that we can estimate interactions as well as first order effects. There is a trade-off between how well we can sample different levels of each factor and how many interactions we are able to estimate.

Ownership Refinement Types for Pointer Arithmetic and Nested Arrays (Artifact) [PDF]
This artifact accompanies the paper "Ownership Refinement Types for Pointer Arithmetic and Nested Arrays." It provides nested_array_ConSORT, a tool for automated ownership type inference and refinement type checking for imperative programs with pointer ...

Sensors, 2019 In this paper, we derive the discrete Fourier transform (DFT) method for direction of arrival (DOA) estimation by generating the massive virtual difference co-array with the nested array. By contrast with the spatial smoothing (SS) subspace-based methods

Ownership Refinement Types for Pointer Arithmetic and Nested Arrays [PDF]
Tanaka et al. proposed a type system for verifying functional correctness properties of programs that use arrays and pointer arithmetic. Their system extends ConSORT - a type system combining fractional ownership and refinement types for imperative ...

A principled approach to programming with nested types in Haskell [PDF]
, 2009 Initial algebra semantics is one of the cornerstones of the theory of modern functional programming languages. For each inductive data type, it provides a Church encoding for that type, a build combinator which constructs data of that type, a fold ...

Advanced Engineering Materials, EarlyView.This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.
