Phase Unmixing : Multichannel Source Separation with Magnitude Constraints

30 Sep 2016Antoine DeleforgeYann Traonmilin

We consider the problem of estimating the phases of K mixed complex signals from a multichannel observation, when the mixing matrix and signal magnitudes are known. This problem can be cast as a non-convex quadratically constrained quadratic program which is known to be NP-hard in general... (read more)
