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: Recently, numerous design schemes for high-order sparse linear arrays (SLAs) have been introduced for underdetermined direction-of-arrival (DOA) estimation based on high-order cumulants, ...

PREFIX SUM ARRAY: A prefix sum array is an array where each element at index i is the sum of all elements from the start (index 0) to index i of the original array.

Array.sum returns NaN if a array item is undefined. this issue is found MooTools More 1.4.0.1 the solution is to check if a item is available.
