Abstract
Modulatable periodic complete complementary codes for cellular CDMA systems have the property of being “modulatable”, like modulatable orthogonal sequences. We propose a generalized method to construct modulatable periodic complete complementary codes composed of expanded modulatable orthogonal sequences. Modulatable periodic complete complementary codes obtained by using the proposed method are composed of n(n⩾2) sets of periodic auto-complementary codes, and each periodic auto-complementary code is composed of n(n⩾2) expanded modulatable orthogonal sequences
