摘　　要：设计船舶无线通信中5G信道资源分配算法,在增大舰船无线通信网络吞吐能力的同时,改善网络通信质量。基于非正交多址技术的上行链路D2D舰船无线通信网络模型,在D2D发送用户与若干个D2D接收用户之间建立数据通信信道,生成D2D用户组,将D2D通信网络最大吞吐量作为优化目标,构建满足蜂窝、D2D用户接收信号SINR阈值等约束条件的5G信道资源分配模型,采用用户-子信道双边匹配算法获取子信道分配策略,利用注水功率分配算法确定D2D用户组功率分配策略,实现舰船无线通信的5G信道资源分配。结果表明:该算法可实现舰船无线通信网络5G信道资源分配,允许40个D2D用户组接入到通信网络中;NOMA传输机制下的网络吞吐量高于OMA机制,数据传输速率达到220 bps以上,干扰度小。Design a 5G channel resource allocation algorithm for ship wireless communication,which not only increases the throughput of the ship wireless communication network,but also improves the quality of network communication.The uplink D2D ship wireless communication network model based on non orthogonal multiple access technology establishes a data communication channel between D2D sending users and several D2D receiving users,generates D2D user groups,and optimizes the maximum throughput of the D2D communication network.A 5G channel resource allocation model is constructed that satisfies constraints such as the SINR threshold of received signals for cellular and D2D users,Using the user subchannel bilateral matching algorithm to obtain the subchannel allocation strategy,and using the water injection power allocation algorithm to determine the D2D user group power allocation strategy,the 5G channel resource allocation for ship wireless communication is achieved.The experimental results show that this algorithm can achieve 5G channel resource allocation in ship wireless communication networks,allowing 40 D2D user groups to access the communication network.The network throughput under the NOMA transmission mechanism is higher than that under the OMA mechanism,with a data transmission rate of over 220 bps and low interference.
