A new method of deconvolution in the frequency domain is proposed. The relationship between the proposed method and traditional Discrete Fourier Transform(DFT) method is also discussed. It can be seen from this paper that the new method based on the DFT techniques can overcomes the difficulties of using traditional frequency methods to do deconvolution, and the deconvolution problem can always be solved with the new method because three are only DFT, IDFT and multiplication calculations. An example is also presented to illustrated the calculation of the method.
