AWGN

代码说明：

  AWGN信道的设计与仿真加性高斯白噪声在通信领域中指的是一种各频谱分量服从均匀分布（即白噪声），且幅度服从高斯分布的噪声信号。因其可加性、幅度服从高斯分布且为白噪声的一种而得名。(Design and Simulation of additive white Gaussian noise AWGN channel in the middle of the field of communication is a uniform distribution of each spectral component (ie, white noise), and the amplitude of the noise signal to obey a Gaussian distribution. Because it can increase resistance, the magnitude of Gaussian distribution and is named after a white noise.)
