英文摘要: Heterogeneous networks with the effective improvement of the coverage and capacity of the wireless communication are recognized as one of the important forms of the future wireless communication. However, heterogeneous networks interference management is facing tough challenges. This problem has drawn great international attention and requires further systematical study on its relevant theory and method. This project attempts to carry out research on theory and method of coordinated interference management and system capacity of the heterogeneous networks. It involves: 1) using stochastic geometry theory to build the theoretical model with the spatial characteristics of the heterogeneous networks; analyzing the statistical distribution of the heterogeneous networks interference; studying the closed form solution and the upper and lower bounds of the heterogeneous networks transmission capacity under the impact of the path loss and shadow fading while illustrating the effects of different channel models on heterogeneous networks capacity.2) focusing on coordinated interference management based on heterogeneous networks, using distributed interference management to overcome the limitedness of heterogeneous networks backhaul.3)exploring the complexity controllable distributed interference management and system opti
