摘要
在V2I网络中,为了提高多车辆通信的总可达率和公平性,研究通感一体化与深度学习辅助V2I通信性能优化问题。采用卷积神经网络与长短期记忆网络相结合的方式用于波束形成预测。该网络包含两个子网络,分别用于获取车辆的状态信息和功率分配方案,然后计算波束形成向量。所设计的网络综合了监督学习和无监督学习的特点,在保证用户公平性的同时,最大限度地提高总可达率。仿真结果表明,与现有的基准方案对比,所提算法能显著提高系统的总可达率和公平性。
In vehicle-to-infrastructure networks,the performance optimization problem of vehicle networking is investigated to improve the overall achievable rate and fairness of multiple vehicles.Deep learning techniques,specifically the combination of convolutional neural networks and long short-term memory networks,are employed for beamforming prediction.The proposed network comprises two sub-networks:one for acquiring vehicle state information and the other for power allocation,subsequently calculating the beamforming vectors.The designed network leverages the strengths of both supervised and unsupervised learning,aiming to maximize the overall achievable rate while ensuring vehicle fairness.Simulation results demonstrate that the proposed algorithm significantly improves the system's overall achievable rate and fairness of vehicles compared to existing benchmark solutions.
