Bilinear inverse problems with sparsity: Optimal identifiability conditions and efficient recovery
… we show is equivalent to a sparsity-projected gradient descent). Under certain assumptions, the unknown gains, phases, and the unknown signal can be recovered simultaneously. Numerical experiments show that power iteration algorithms work not only in the regime predicted by our main results, …
