sine wave 设置中有个仿真步长 （Sample time）默认为0，这时候如果你的频率过高就会出现这种情况，将其设置为1e-6左右，就可以解决这个问题。
楼主设定的sample time是1s，Samples per period设定的是5，也就是说一个正弦波周期是5s。得出的频率是0.2hz，角速度是1.2566。freq这个值指的不是f类似于我们学的w角速度。你出现的问题估计是你打错了，我用simulink仿真出来的是对的。
1. matlab 中simulink 里的sine wave 模块可以是连续的也可以是离散的 2.当将Sample time参数设置成0时，它就是连续的模型，设置成大于零时，就是离散的模型，具体可以看help 3.你说的“AWGN Channel”我没看懂啥意思，指的是什么？
