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: https://github.com/igorauad/awgn_matlab Shortcut to download the script: https://github.com/igorauad/awgn_matl...
