向己知信号加入10%RMS noise-to-signal ratio高斯白噪声,急!

如何向一个己知信号中加入10%RMS noise-to-signal ratio高斯白噪声?
论文中是这样写的
A separate white noise process with 10% RMS noise-to-signal ration is superimposed to both the exact analytical signal!
非常急!
谢谢!

你先计算好 exact analytical signal的rms值R,然后加入0.1*R*randn(1,t). t为exact analytical signal的长度
