理论知识是用来指导具体实践的。本文在深刻理解通信系统理论的基础上利用 MATLAB 强大的仿真功能，设计了许多具体的通信系统仿真模型。在仿真模型设计过程中，本文对模型设计的目的、具体的结构组成、仿真流程以及仿真结果都给出了具体详实的分析和说明。(Theoretical knowledge is used to guide the specific practice. In this paper, a deep understanding of the theory of communication systems using MATLAB based on the powerful simulation function, the design of a number of specific communication system simulation model. In the simulation model of the design process, this article is designed on the model, the specific structural components, simulation and flow simulation results are given specific and detailed analysis and description.)

用matlab编写的，有限元三维梁单元的单元刚度矩阵计算程序，各节点6个自由度。(prepared by the three-dimensional finite element beam element of the element stiffness matrix calculation program, the 6-DOF nodes.)

说明：  设计一个模糊PID控制器,以及倒车系统simulink系统，使其可是实现对倒车系统的的优化控制。(Design a fuzzy PID controller, and the reversing system simulink system, so that it can achieve optimal control of the reversing system.)

Okumura analyzed path-loss characteristics based on a large amount of experimental data collected around Tokyo, Japan. He selected propagation path conditions and obtained the average path-loss curves under flat urban areas. Then he applied several correction factors for other propagation conditions, such as: Antenna height and carrier frequency Suburban, quasi-open space, open space, or hilly terrain areas Diffraction loss due to mountains Sea or lake areas Road slope Hata derived empirical formulas for the median path loss (L50) to fit Okumura curves.
