Abstract: In this paper, we investigate a near-field wideband multiuser communication system based on the symmetric nested array (SNA), which is formed by nesting a dense subarray within a uniformly ...

This repo provides a set of useful functions for operating on sparsely stored arrays. This is extremely useful for significantly reducing storage and minorly improving runtime when you have high ...

Abstract: Sparse arrays have been recently applied to spectral sensing of wideband spectrum where the array is configured to estimate the directions of co-frequency emitters and also reconfigured, ...

This project implements sparse data structures (1D sparse array and 2D sparse matrix) using doubly linked lists. Instead of storing large arrays and matrices full of zeros (wasting time and memory), ...

R-MXAS is a revolutionary aerospace architecture for realizing a synthetic aperture imaging radiometer (SAIR) in a manner affording unprecedented sparsity in terms of number of antenna elements. As ...

In today's rapidly evolving smart vehicle technology landscape, Changan Automobile (stock code: 000625) has once again attracted industry attention. According to the latest news from Securities Star, ...

In a past life, I've toyed with trying to implement something like this (assuming you're talking about interferometry). The principal issue (IME) is data volume/bandwidth. Interferometry using ...
