[Authors] S. M. Masharsky and K. Yu. Tsvetkov [Title] On cross-correlation function of discrete signals in Vilenkin-Chrestenson basis [AMS Subj-class] 42C10 Fourier series in special orthogonal functions [Abstract] This paper presents the results of generalization of well-known relation for correlation functions of complex discrete signals. The proofs of corresponding statements are given. The sets of delta-correlated complex discrete signals in Vilenkin-Chrestenson basis are constructed. These sets of signals can be used in spread spectrum communication systems with code division multiple access. [Comments] 8 pp., Russian [Contact e-mail] smash@scientist.com wavelet3@mail.ru
