Number of integers between 1 and N that are coprime to N

WebA coprime array consists of two ULAs, which have M and N elements. Herein, M and N are coprime numbers, and the distances of the two ULAs are N d and M d, respectively. Although there is ambiguity in the angle estimation for each ULA, this ambiguity can be eliminated via the coprime characteristic. nwo coin
