Abstract

The device-to-device (D2D) technology performs explicit communication between the terminal and the base station (BS) terminal, so there is no need to transmit data through the BS system. The establishment of a short-distance D2D communication link can greatly reduce the burden on the BS server. At present, D2D is one of the key technologies in 5G technology and has been studied in depth. D2D communication reuses the resources of cellular users to improve system key parameters like utilization and throughput. However, repeated use of the spectrum and coexistence of cellular users can cause co-channel interference. Aiming at the interference problem under the constraint of fair resource allocation and improving the system throughput, this paper proposes an effective resource optimization scheme based on the firework method. The main idea is to expand the weighted sum rate and convert the allocated resource expression into fireworks to determine the correlation matrix. The simulation results show that, compared with the existing scheme, this scheme improves system performance by reducing interference.
