为了更好地设计通信系统，我们需要对无线环境下收端信号的统计特性进行研究。考虑以下场景：环境中有很多障碍物，发射端至接收端没有视距可达路径。 假设收发端距离很远（500m以上），障碍物数量很大（N>50），并在空间中随机分布。同时假设各路反射信号到达接收端的强度相同（能量E=1），信号载波频率为1GHz，请进行仿真，探索以下问题： （1）接收到的正弦波的相位服从什么分布？ （2）计算接收信号的幅度的均值和方差，并绘制其概率密度函数图。 （3）学习“Rayleigh分布”相关内容，并绘制参数为√NE的Rayleigh分布概率密度函数，计算其期望和方差的理论值。这些理论结果与仿真得到是否一致？ （4）固定障碍物的位置，让接收机分别以速度1m/s和10m/s的速度运动，绘制接收信号的包络随时间变化的曲线。并观察和对比两条曲线，能否有什么发现？(In order to better design the communication system, we need to study the statistical characteristics of the received signal in the wireless environment. Consider the following scenario: There are many obstacles in the environment, and there is no line-of-sight path from the transmitter to the receiver.)
