WebIn this paper we investigate fundamental properties of the (M,N,L)-complete complementary codes proposed by Suehiro and Hatori. The (M,N,L)-complete complementary code satisfies: (a) for each set, the sum of autocorrelation functions is equal to zero except for the zero shift, and (b) for any two different sets, the sum of cross-correlation functions are equal to … WebAnswer Explanation. 6) The basic properties of DFT includes. 1) Linearity. 2) Periodicity. 3) Circular symmetry. 4) Summation. a. 1, 2 and 3 are correct. b. 1, 2 and 4 are correct. c. 1 … direcpath plans
