Abstract: This article presents a deconvolution algorithm for high-resolution acoustic imaging, specifically tailored for small-element acoustic vector-sensor (AVS) arrays. While existing fourth-order ...

Suppose an array of length n sorted in ascending order is rotated between 1 and n times. For example, the array nums = [0,1,2,4,5,6,7] might become: [4,5,6,7,0,1,2] if it was rotated 4 times. [0,1,2,4 ...

You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise) in-place. You have to rotate the image in-place, which means you have to modify the input 2D matrix ...

Abstract: The sparse array could reduce the cost of physical antennas. However, implementing wideband beamforming directly based on the covariance matrix of the received signals from the sparse array ...
