In the paper, the rows of W
are defined as w^H
, so the algorithm is just consistent with this definition.
To see it, you can breakdown line 162 in two steps
w = np.linalg.solve(WV, eyes[:, :, s])
W[:, s, :] = np.conj(w)
If you want to store the non-conjugated demixing filters in W
, then you will need to add a conjugate operation around W
in all other equation, e.g., (25).

OK, got it.
two more questions please:
- About the scale restoration of the signal. The paper cited this paper "An Approach to Blind Source Separation Based on Temporal Structure of Speech Signals" but I don't see in the paper the projection_back function implemented here( ). Can you direct to the paper of this implementation?
- About the normalization to prevent ambiguity(
