Thank for your amazing work and it really helps me a lot in my research.
But I met a problem when I run your BSS code using a four channels data, could you please tell me how to change your BSS code to support multi-channel processing?
Best Regards.
Thanks in advanced!

Hello,
Thanks for watching! My provided code on github is only supported for 2 channel BSS, the demixing matrix can be acquired analytically by solving the 2 x 2 generalized eigendecomposition problem.
However, for channels more than 2, there is no closed-form solution, instead, the matrix inversion lemma can be used to solve the problem iteratively. Please refer to the paper for the detailed theory (section 4.2). If the computational complexity is not considered, the easier way is to perform matrix inversion directly by matlab’s inv function (Algorithm 1 in the paper).
