CDMA Characteristics of Complex Orthogonal Codes for Chaos-OFDM Communications Systems
Ken Umeno (National Institute of Information and Communications Technology) NLP2008-79
Abstract (in Japanese) (See Japanese page) 
(in English) Recently reported complex chaos orthogonal codes specified by prime number and its primitive root can construct unitary transformations by their orthogonality and thus, construct a new type of OFDM communication systems, namely, chaos-OFDM communications systems. Here, we report cross-correlation properties for different complex chaos orthogonal codes, which is nothing but a CDMA characteristic of the codes.
