Transmission Scheme and Performance Analysis of Complementary Coded Full Duplex Communication System

This paper studies a transmission scheme for in-band full-duplex communication system, which is established on the base of complementary codes. Having ideal correlation properties, complementary codes are capable of providing effective mitigation of self-interference (SI) introduced by co-frequency co-time full-duplex (CCFD) communications, an efficient multiple access for multiple users as well as high-performance resistance against multi-path interference under fading channels. In this paper, we briefly investigate the basic structure and correlation properties of complementary codes. As the core part, complementary coded full-duplex multiuser communication system is set up, and more details of transmission signals and channels are presented. Then the mathematical analysis of bit error rate (BER) and outage probability (OP) verifies its strong capability of various interference suppression. Finally Monte-Carlo simulations are implemented to confirm theoretical derivations revealing that the system transmission performance will hardly worsen with the increasing intensity of SI in a certain range.
