Refer to BigOMethods.png for the Big-O of all methods in isolation, and taking into account array manipulation. Please note that values are not exact, as the circular array often cuts runtimes in half ...

Abstract: Due to the excellent directivity and strong beam steering capabilities, circular concentric array antenna (CCAA) are frequently preferred over large circular array antennas. In contrast to ...

Given an array of integers arr[] in a circular fashion, return the maximum sum of a subarray that can be obtained assuming the array is circular. Note: The solution should account for both regular and ...

Abstract: The beamforming performance of the uniform circular array (UCA) in near-field wideband communication systems is investigated. Firstly, the unique beam squint effect in near-field wideband ...
