Short Time DFT Hilbert変換器のための高速化処理

Abstract

An exact realization of the Hilbert transformer has been previously discussed with employing new concept of instantaneous spectrum on the basis of frequency domain Hilbert transform. The FFT processing structure yields some advances to the short time DFT Hilbert transformer to overcome the absolute defect by reducing the great processing amount without any loss of generality via employing interpolation of multi-rate sampling. This nobel transformer is also discussed to prevent the functional precision from synchronization error which occurs either between analyzer and synthesizer within the nobel transformer or between two nobel transformers installed at sending and receiving sites in radio communication systems.
