D2D通信中基于信噪比均衡的资源分配算法
Resource Allocation Algorithm Based on SNR Equalization in D2D Communication
摘要
Abstract
For Device-to-Device(D2D) links sharing the radio resources with the cellular links in cellular network, this paper proposes a resources allocation algorithm based on Signal to Noise Ratio(SNR). It establishes a convex optimization problem to maximize total system throughput on the basis of optimizing the received interference power and balancing SNR of all users. It solves the convex optimization problem using Lagrange multiplication method, and thus obtains the closed-form solution for this convex optimization problem. Simulation results illustrate that the algorithm can improve the SNR of the cellular links and increase the total system throughput effectively.关键词
