The Multi-Level Dilated Nested Array for Direction of Arrival Estimation
IEEE Access, 2020 In this paper, a more generalized dilated nested array (DNA) named multi-level dilated nested array (multi-level DNA), which further extends the original DNA to the general situation and improves the direction of arrival (DOA) estimation performance, is ...

Fractional Low-Order Moments Based DOA Estimation With Co-Prime Array in Presence of Impulsive Noise
IEEE Access, 2021 Direction of arrival (DOA) estimation with co-prime array is a hot issue in array signal processing. By using co-prime array structure, the degrees of freedom has been greatly improved, which can estimate much more sources than that of the conventional ...

Spatial Spectrum Estimation of Co-Channel Direct Signal in Passive Radar Based on Coprime Array
Remote Sensing, 2022 The received signal of passive radar based on mobile communication signals contains direct and multipath interference (DMI) signals from multiple co-channel base stations (CCBS). The direct signal spatial spectrum of each CCBS should be obtained first to

Sparse convolutional array for DOA estimation
EURASIP Journal on Advances in Signal Processing, 2022 Array signal processing plays an important role in many areas. Besides the Uniform Linear Array, there are many sparse array that have been proposed, for example, Minimum-redundancy array, Co-prime array, nested array, etc.

Co-array Music under Angle-Independent Nonidealities [PDF]
2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020 The difference co-array is crucial in determining the number of resolvable sources in direction-of-arrival (DoA) estimation. This virtual array of pairwise sensor position differences enables sparse arrays to identify vastly more sources than sensors. However, the idealized assumptions giving rise to the co-array, such as isolated omnidirectional gain ...

Co-Array Collectives: Refined Semantics for Co-Array Fortran [PDF]
, 2006 Co-array notation provides a compact syntax for programming parallel programs. Co-array Fortran (CAF) introduced and implements this notation, and CAF is currently proposed as an extension to the Fortran language standard. We believe that co-array notation requires a revised semantic definition beyond that specified by CAF for both pragmatic reasons ...

Wideband DOA Estimation on Co-prime Array via Atomic Norm Minimization
Energies, 2020 This paper introduces a low complexity wideband direction-of-arrival (DOA) estimation algorithm on the co-prime array. To increase the number of the detectable signal sources and to prevent an unnecessary increase in complexity, the low dimensional co ...

Co-array Fortran for parallel programming [PDF]
ACM SIGPLAN Fortran Forum, 1998 Co-Array Fortran, formerly known as F -- , is a small extension of Fortran 95 for parallel processing. A Co-Array Fortran program is interpreted as if it were replicated a number of times and all copies were executed asynchronously. Each copy has its own set of data objects and is termed an image.

Scientific Reports, 2022 Cochlear implants (CI) restore hearing of severely hearing-impaired patients. Although this auditory prosthesis is widely considered to be very successful, structural cochlear trauma during cochlear implantation is an important problem, reductions of ...

A Fast and Robust DOA Estimation Method Based on JSVD for Co-Prime Array
IEEE Access, 2018 Compared with the uniform linear array, the co-prime array can obtain a large array aperture with fewer array elements, which is good to improve the accuracy of direction-of-arrival (DOA) estimation.
