Abstract: Sparse arrays designed based on fourth-order difference co-array (DCA) can achieve significantly higher uniform degrees-of-freedom (uDOFs). However, most existing fourth-order sparse arrays ...
Abstract: Large‐aperture antenna arrays promise fine angular resolution, but their dense layouts usually lead to prohibitive cost and design complexity. Sparse arrays present a compelling alternative, ...
Solved the Sparse Arrays problem on HackerRank today—simple on the surface, but a great exercise in efficiency. The task was to count how many times each query string appears in a list of strings.
