Abstract
This paper introduces an algebraic approach to generate the super-set of perfect complementary (PC) codes suitable for interference-free CDMA applications. The code design methodology proposed herein takes into account major impairing factors in real applications, such as MAI, multipath effect, asynchronous up-link transmissions and random signs in consecutive symbols. Two important conclusions will be drawn by the analysis given in this paper. First, implementation of an interference-free CDMA will never be possible unless using proper complementary code sets, such as the PC code sets proposed in this paper. Second, to enable interference-free CDMA operation, the flock size of the PC codes must be made equal to their set size. The so generated CDMA code sets can be applied to implement a new CDMA architecture offers a performance limited only by noise.
