%X Code Division Duplex (CDD) is a novel duplex technique for next generation mobile communication systems. It supports the transmission for uplink and downlink at the same frequency band and the same time interval. As the power levels of uplink and downlink are of potentially great difference, the signals over uplink and downlink channels may interfere with one another seriously. In order to solve this problem, this paper proposes a novel technique to suppress the interference between uplink and downlink. First, several kinds of interferences are analyzed, and then an interference cancellation scheme combined with distributed antennas technique is proposed for base station. The interferences between mobile stations can be mitigated by the presented time slot assignment strategy based on the location technique. Finally, numerical calculations and simulation results show the effectiveness of the proposed methods.
