Abstract: An N-element array with receivers subject to an N-point spatial fast Fourier transform (FFT) leads to N directionally orthogonal radio frequency (RF) beams. FFTs are fast algorithms for ...

Imagine you’re sitting in on a fourth-grade math class, witnessing a multiplication lesson. Instead of splitting the room between fast finishers and students who still need support, the teacher gives ...

Electro-optical detectors are used to measure or sense the radiation emitted or reflected by objects within the detector’s optical field of view (FOV). Passive systems operate without any illumination ...

This package supports lazy analogues of array operations like vcat, hcat, and multiplication. This helps with the implementation of matrix-free methods for iterative solvers. The package has been ...

Abstract: Real-time applications like audio signal processing and wireless communication highly demand the need for powerful and efficient multiplier and accumulator units (MACs) for achieving high ...

Computer scientists have discovered a new way to multiply large matrices faster than ever before by eliminating a previously unknown inefficiency, reports Quanta Magazine. This could eventually ...

A coprime array with fewer sensors can achieve the same resolution as a uniform linear array. However, when detecting co-frequency targets, there can be prominent false alarms due to overlaps between ...
