基于毫米波和轨道角动量的下一代手机无线通信技术设计

Design of next generation mobile wireless communication based on millimeter wave (mm-wave) and orbital angular momentum (OAM)

在第四代通信技术中,由于带宽有限和通信技术的限制,固有的通信技术很难将通信的性能大幅提升。因此将毫米波和轨道角动量技术结合进行仿真,为基于两种技术的下一代手机通信系统提供理论上的可能性。传统的研究仅将轨道角动量和毫米波运用于室内短距离点对点信号传输,不能体现在区域中的网络表现,不适用于实际情况中。本研究使用全新的区域分布模型和阈值判断算法,从而更真实的表现用户与基站的分布。为改善通信系统,多输入输出系统(MIMO)、多频复用技术和奇异值分解法(SVD)将被用于仿真中的模型建立。蒙特卡洛算法将在仿真中应用,从而得到通信系统最接近现实的仿真。为突出优势,第四代通信技术的模型也将在仿真中建立。仿真结果表明,毫米波和轨道角动量模型可以在区域中正常使用并且各种表现大大优于第四代通信技术。

Due to the limitation of bandwidth and communication technologies in 4G,it is difficult to improve mobile wireless network effectively.However,mm-Wave provides a wide bandwidth and OAM supplies a new modulation way.In this research,these two methods are combined to improve the next generation mobile wireless network.Former researches are mainly about indoor short distance line of sight (LOS) wireless communication.It cannot be used in practice.This research creates brand new algorithms to simulate users and environment in real lives.These methods called Stochastic Geometry Model and Threshold Model.In order to improve the performance,MIMO,Multiple Frequency Reuse and SVD are used in this article.Monte-Carlo Simulation is used to get the normal situation.Moreover,4G model is built and compared to the new model.Finally,it can be seen that this new idea can be used in mobile communication and its performance is much better than that of 4G.
