摘要
摘要:针对异构网络中D2D通信复用蜂窝用户频谱时存在的频谱分配问题，该文提出一种基于改进离散鸽群优化(PIO)算法的D2D通信资源分配机制。通过设置信干噪比(SINR)门限值来保证用户的通信服务质量(QoS)，采用功率控制算法为用户设置发射功率，使用基于运动权值的二进制离散鸽群优化(MWBPIO)算法为D2D用户进行资源分配，并将D2D通信技术与中继技术进行有效结合，为边缘用户建立D2D中继链路，保证边缘用户的通信质量，最大化系统性能目标。仿真结果表明，该方案有效抑制了异构通信系统中引入D2D用户后导致的干扰问题，提高了边缘用户的通信质量和系统的频谱利用率以及系统的能效。

Abstract:For the problem of spectrum allocation in the multiplexing of cellular user spectrum resources by Device-to-Device (D2D) communication in heterogeneous networks, a D2D communication resource allocation mechanism based on improved discrete Pigeon-Inspired Optimization(PIO) algorithm is proposed. The user's Quality of Service (QoS) is guaranteed by setting the Signal-to-Interference plus Noise Ratio (SINR) threshold, the transmitting power is set for users by power control algorithms. To allocate resources for D2D users, the Binary discrete PIO based on Motion Weight (MWBPIO) algorithm is used. To ensure the communication quality of edge users, the D2D communication technology and relay technology are used to establish D2D relay links, so then the performance of system can be maximized. Simulation results show that the proposed scheme can effectively suppress the interference caused by the introduction of D2D users in heterogeneous communication systems. Moreover, the proposed scheme can effectively improve the communication quality of edge users, and improve the utilization of spectrum resources and the performance of the system.
