An improved fast implementation method for FFT pruning algorithm

Abstract

For the application of increasing the FFT's spectrum resolution by zero padding, this paper proposes an improved fast implementation method for FFT pruning algorithm, in which only part spectral of the whole FFT's spectral need to be calculated. According to the structural characteristics of input data and output data, the proposed method in this paper… (More)
