Gaussian White Noise Generator block





In communication system simulator, a Gaussian noise generator is generally computed using the box Muller law. This method allows noising both amplitude and phase a given complex value. It is defined with these two equations:


where $ \tilde{p}$ and $ \tilde{q}$ are two uniform random variables, $ \sigma$ the variance of the noise source and $ \tilde{I}$ $ \tilde{Q}$ the real and imaginary part of the noisy complex sample.
