通信原理实验_Matlab仿真基础
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.)
