Abstract: The invention discloses a D2D communication interference management method based on joint interference alignment and power optimization, which mainly solves the problem that the interference intensities from different interference links are different caused by that the existing method cannot guarantee the interference alignment feasibility and the path losses of different interference links are different The implementation process is as follows: the system decomposes the optimization problem into three sub-problems, and obtains a second-best solution of the original problem by solving these three sub-problems in turn: firstly selecting an appropriate interference link under the premise of ensuring that the interference alignment is feasible for interference alignment, and calculating theconnectivity coefficient matrix a; secondly, designing the partial connectivity interference alignment pre-coding V and the decoding matrix G for the selected interference link; and finally, performing iterative convex approximation power optimization for the remaining interferences The invention may increase the degree of freedom of D2D and cellular communication links while effectively improving the network throughput
