Abstract

Based on the uplink mode in cellular network, device to device (D2D) multi-user shared channel can effectively improve the spectrum utilization and overall communication capacity of the system, however, it will also bring serious interference problems, which will affect the end-user experience. For interference problems, In this paper, in a D2D communication system where users and cellular users coexist, multiplexing resources are allocated according to the minimum interference. By establishing the objective function of minimum interference and using the Hungarian algorithm to optimize this objective function, the total interference to D2D users in the system is minimized, and the D2D users can access the system the most. The simulation results show that the scheme can reduce the interference of D2D users to cellular users within a certain range, and also maximize the number of D2D users in the access system.
