Location and partition where template signals most differ for informed source separation
I state the problem in continuous time, yet of course it is discrete in practice, and time here stand for any ordinal axis (like frequency, scale). I observe a real signal $y$ which is supposed to be ...

Signal Separation (constant modulus)
I am trying to separate two source signals, that have constant envelope. The things is that the mixture if forming a Torus, and I am not sure about which algorithm is the most adapted to the situation....

Fiber Photometry (Fluorescence) Signal Preprocessing through Source Separation and Baseline Correction
I am working on preprocessing fiber photometry data. The data collection involves inserting fibers into an animal, where the reflection of specific wavelengths of light is captured. We collect two ...

How to retune this mixture of 2 close-frequency sinusoids?
I have a signal which is a mixture of 2 close-frequency sinusoids, something like 1320 Hz and 1325 Hz, with an amplitude envelope which is typical for a musical instrument (ADSR).
$$s(t) = a_1(t) \sin(...

How would you compute Fourier transform of a real world signal where the signal keeps getting updated (not a static one)?
Crossposted at Electrical Engineering SE
A very naive question: How do we use Fourier transform for real world signals - for which you have the information only up to the present instant (and the ...

Deconvolution of a ground-penetrating radar signal for further convolution with a desired source signal
I am following the instructions of this paper (https://www.earthdoc.org/content/journals/10.3997/1873-0604.2003015) to process a ground-penetrating radar (GPR) signal (a discrete signal sampled at a ...

Good models to separate speech and noise?
I have an audio clip containing speech and noise. I want to separate the noise signal from the speech signal.
I've looked at some deep-learning based models, but they only remove the noise, without ...

What is the relationship between beamforming and Independent Component Analysis (ICA)?
My first inclination when thinking about the Cocktail Party Problem would be to use adaptive beamforming to isolate different signals, but this does not seem to be how the problem is commonly thought ...

How can I perform semi-blind non-orthogonal successive interference cancellation (SIC) / source-separation with SISO in 4G/5G Downlink?
Semi-blind non-orthogonal successive interference cancellation in the single antenna case with 4G/5G signals (applies generally though).
This is very similar to NOMA in 5G, except that I have no ...
