Application of Fourier Transform in the Signal Decomposition by Threshold Setting
Abstract：There are problems that BRATUMASS system signal analysis. Based on weak function of generalized functions in the Hermite basis function decomposition, this paper proposes the method of signal decomposition by the signal spectrum amplitude, according to some set threshold sequence to be. In addition, the method discussed how to determine the sequence of the lower threshold from the probability distribution of the signal amplitude spectrum. The process of determining the lower limit and decomposing the actual signal shows that the separation can be a clearly show the synthesis of the echo characteristics of the organization and the extracted lower limit can be close to the actual value of the characteristic parameters.
