The problem considered is that of reconstructing a signal from the Fourier intensity of the signal and the Fourier intensities of two windowed signals: one by a window w(n) and the other by its complementary window (1-w(n)). Several conditions are developed under which a signal can be uniquely specified to within several trivial ambiguities such as sign, translation, and time reversal from the given conditions. A possible reconstruction algorithm derived from the Gerchberg-Saxton algorithm is presented.
