首先分析了瑞利衰落信道统计特性，并在此基础上给出了clarke模型，然后提出仿真方法，包括成形滤波法、jakes仿真模型及其多种改进方法，接着阐述了上述仿真模型的软件实现过程，并利用matlab进行了计算机仿真，然后给出衰落信号的仿真信号和分析结果，仿真结果证明了提出的仿真模型与理论曲线匹配度高，可以很好地模拟无线衰落信道(First analyze the statistical properties of the Rayleigh fading channel, and clarke model is given on this basis, and then asked the simulation methods, including the forming of the filter method, the the jakes simulation model and a variety of improvement, then described the simulation model of the software implementationprocess, and using matlab computer simulation, and then gives the simulated signals and analysis results of the fading signals, simulation results show the proposed simulation model with the theoretical curve to match high, can simulate the wireless fading channel)

GPS 软件接收机是一个用matlab编写的一个简单软件接收机(Software GPS receiver)

说明：  matlab 实验手册和初学者使用过程中需要注意的几点重要说明(matlab beginners course of several important to note that)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)
