### System Identification with a Limited Bandwidth Input Signal and Region of Interest

The reason x[n] must be white is because the solution will effectively spectrally weight the channel response based on the amount of energy present in each spectral frequency location. A white noise ...

### Denoise Techniques When Clean Signal and Pure Noise Are Available

If noise is available and it is sure that noise will remain same/almost same for entire duration then one can go for Spectral Subtraction or Wiener filter techniques for noise reduction, which will ...

### How to extract features from nonstationary signal using SVD (singular value decomposition)?

What you're describing is a spectrum estimation based on signal representation in a vector space spanned by eigenvectors of a particular matrix generated from your signal observation. That reminds me ...

### MUSIC algorithm derivation

The piece I was missing was the distribution of the initial phase values $\varphi_1$ and $\varphi_2$. It is standard to assume that these are uniformly distributed [^]. This leads to:  \mathbf{R_x} =...
