We discuss the solution and cost analysis for these configurations. It is shown that the problem can be reduced to a least squares problem which can be solved with fast iterative techniques.EnglishFourier transformsIterative methodsLeast squares approximationsFractional Fourier domain filteringMulti-channel filteringMulti-stage filteringSignal filtering and predictionConference Paper10.1109/TFSA.1998.721466
