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, non-conventional odd-order statistics, especially the third-order cumulants (TOCs), have been introduced to direction-of-arrival (DOA) estimation based on third-order nested array ...

- Iterate through the array using two nested loops. - For each element nums[i], check every element after it nums[j]. - If nums[i] + nums[j] equals the target, return their indices. - This ensures all ...
