- This paper focused on the problem of securing the globally optimum solution in a consecutive 2-stage masking operation on fractional Fourier transform domains, as opposed to only being able to determine a local sub-optimal one. Applying the optimal masks will of course yield the best signal restoration results but finding the global solution in a non-convex problem is in general extremely difficult or even impossible. The paper demonstrates how a specially modified filled function-based strategy is indeed able to detect the global optimum solution in the above problems
