How to generate AWGN with correct PSD on MATLAB

Описание к видео How to generate AWGN with correct PSD on MATLAB

This video explains how to generate the additive white Gaussian noise (AWGN) with a given power spectral density (PSD). First, given the PSD, the total power of the noise is calculated. Then, the time-domain noise is generated. Finally, the PSD of the discrete sequence is estimated using the FFT.


Expected background:
- Basics of stochastic process: expected value, mean, variance, total power of a random process
- Discrete Fourier Transform (DFT)
- DFT frequency spacing
- Power spectral density

The script is available at the GitHub repository:
