What is source separation approach?

Source separation, blind signal separation (BSS) or blind source separation, is the separation of a set of source signals from a set of mixed signals, without the aid of information (or with very little information) about the source signals or the mixing process.

How do you separate two signals?

You can then get the separated signals by creating two copies (one for each component you want to recognize) of the Fourier-domain signal, zeroing unwanted Fourier coefficients (zeroing different sets of coefficients in each of the two copies), and reconstructing the two signals.

How does blind source separation work?

Blind Source Separation (BSS) refers to a problem where both the sources and the mixing methodology are unknown, only mixture signals are available for further separation process. In several situations it is desirable to recover all individual sources from the mixed signal, or at least to segregate a particular source.

Which algorithm is used to separate mixed signals from different sources?

Single Channel Blind Source Separation (SCBSS) has had many algorithms for artificial mixed signal, where the number of mixing sources is assumed to be known, and mixed signal used in validation algorithm only contains two signal sources.
