Abstract：With the development of wireless communication system， the existing interference theory faces the challenges from the demand of high spectral efficiency， multi-user capacity， and various wireless applications， and those from the high speed changing complex communication scenarios.It is neccessary to develop new interference theory， which includes how to utilize the characteristics of signals to decern the different users， investigate the separatable mechanism and methodology of mixed signals， how to establish the suitable network model by the intrinsic characteristics of different interference scenarios， and develop the related the theory and methodology on "interference avoidance"， "inteference coordination"， and "interference utilization"， so as to match the complex variable wireles interference scenarios. By this project， we will establish the theory on interference coordination and interference utilization for the broadband wireless communications in high mobility scenarios， propose the methods on interference coordination and utilization based on interference aligment， network MIMO and network coding， and perform experimental test for the proposed methods. By this project， we will try to solve problem on "separable mechanism of mixed signal and interference theory".
