Hardware Acceleration of MUSIC Algorithm for Sparse Arrays and Uniform Linear Arrays
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2022Multiple Signal Classification (MUSIC) is a high-performance Direction of Arrival (DOA) estimation algorithm, which has been widely used. The algorithm needs to calculate the covariance matrix, eigenvalue decomposition and spectral peak search.

Compilation of Sparse Array Programming Models [PDF]
Proceedings of the ACM on Programming Languages, 2021 This paper shows how to compile sparse array programming languages. A sparse array programming language is an array programming language that supports element-wise application, reduction, and broadcasting of arbitrary functions over dense and sparse arrays with any fill value.

Machine Learning-Based Direction-of-Arrival Estimation Exploiting Distributed Sparse Arrays
Asilomar Conference on Signals, Systems and Computers, 2021Distributed sparse arrays, consisting of multiple subarrays, facilitate a higher number of degrees of freedom and enhanced direction-of-arrival (DOA) estimation performance beyond what is offered by single uniform linear arrays.

Rank Properties of Manifold Matrices of Sparse Arrays
Asilomar Conference on Signals, Systems and Computers, 2021It is well known that the manifold matrix of a sensor array has to satisfy certain rank conditions in order for certain algorithms such as MUSIC and ESPRIT to work without creating ambiguity.

Direction-of-Arrival Estimation Exploiting Distributed Sparse Arrays
Asilomar Conference on Signals, Systems and Computers, 2021In this paper, we present a novel direction-of-arrival (DOA) estimation strategy that exploits distributed sparse sensor arrays and structured matrix completion-based information fusion techniques to provide superior DOA estimation performance with ...

Grating Lobe Reduction in Sparse Arrays with a Metasurface Lens
2021 Cross Strait Radio Science and Wireless Technology Conference (CSRSWTC), 2021Starting from the theory of antenna arrays, this paper proposes a new method to suppress the grating lobes of a sparse array. By loading a metasurface lens with subwavelength periodic configuration and the control of the transmission phases, a new sparse

Spray: Sparse Reductions of Arrays in OPENMP
2021 IEEE International Parallel and Distributed Processing Symposium (IPDPS), 2021We present SPRAY, an open-source header-only C++ library for sparse reductions of arrays. SPRAY is meant for applications in which a large array is collaboratively updated by multiple threads using an associative and commutative operation such as +=. Especially when each thread accesses only parts of the array, SPRAY can perform significantly better ...
