A subarray of an -element array is an array composed from a contiguous block of the original array's elements. For example, if array=[1,2,3], then the subarrays are [1],[2] ,[3],[1,2] ,[2,3] and ...

The length of the array is in range [1, 20,000]. The range of numbers in the array is [-1000, 1000] and the range of the integer k is [-1e7, 1e7]. * Approach: PreSum + HashMap * 这道题目与 Maximum Size ...

Abstract: This paper works on the pattern synthesis for uniform subarray problem which is seldom researched, and a new pattern synthesis approach based on multi-point array response controlling is ...

Sometimes element feeds are shared across subarrays to create virtual arrays. The key point is that the total number of transmit/receive modules is less than the number of antenna elements for each ...

Abstract: The paper presents a comparison of two subarray based beamforming techniques namely the ... First the CBF technique is examined with three small sensor arrays called subarrays, separated by ...
