Abstract:
1. A signal processing method for processing a plurality of input frequency domain data within a frequency band, each of the input frequency domain data having magnitude and phase characteristics and being associated with a phase parameter that corresponds to the phase characteristic thereof, said signal processing method comprising the steps of: a) arranging the input frequency domain data in sequence on a variable axis; b) rearranging, using a sequence processing unit, positions of the input frequency domain data on the variable axis, including calculating a displacement value (ΔT) for at least one of the input frequency domain data with reference to at least the phase parameter thereof, and moving said at least one of the input frequency domain data from an initial position on the variable axis to an adjusted position on the variable axis with reference to the displacement value thus calculated; and c) combining the rearranged input frequency domain data that are disposed on the same position on the variable axis to result in a plurality of processed frequency domain data.
