Abstract

This paper introduces an algebraic approach to generate super-set of perfect complementary (PC) codes suitable for interference-free CDMA applications. The approach takes into account major impairing factors in real applications, such as MAI, multipath interference, 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 some properly selected 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. An implementation scheme of a CDMA system based on the PC codes will also be presented and its performance is compared with traditional CDMA systems by simulations, whose results show that the proposed new CDMA architecture offers a performance limited only by noise.
