英文摘要： In this project, we will study the capacity region as well as the efficient transmission schemes for cyclic interference channels,and propose an efficient transmission scheme which is suitable for cyclic interference channel. Specifically, the following issues are involved: determination of the capacity region, inner bound, outer bound and degrees of freedom for the single-antenna and MIMO multi-user cyclic interference channel; analysis of the performance of the existing transmission schemes based on the multi-user cyclic interference channel; development of the time-frequence-based joint interference alignment algorithm which is suitable for the cyclic interference channel; and the joint optimization of energy-efficiency/time/space resources is investigated for the MIMO cyclic interference channel. On this basis, the coded transmission scheme for approaching the fundamental performance limits will be designed with the use of dirty paper coding (DPC) and rateless coding.
