Generalized orthogonal complementary codes for cdma wireless communications

The spread spectrum signals have large application in modern personal communication systems, but they must meet many requirements, addressed especially to theirs correlation properties. With regard to these requirements, recently some theorists proposed a new architecture for the next generation wideband wireless communications, based on so named Orthogonal Complementary Codes (OCC). The most distinguishable advantage of this architecture is possibility to operate without multiple access interference. As a result, the system capacity, secrecy, and electromagnetic Compatibility can he improved significantly. Due to positive features of the OCC in our paper we study the OCC in a wider frame, when phase manipulation could he arbitrary (i.e. not necessarily binary). On this base we prove a common method for creating of generalized OCC with unlimited code length and outline relations among some classes of signals with good correlation properties.
