FFT Spectrum Computation with High Performance Based on Fixed-Point DSP
Based on some established Fast Fourier Transform (FFT) spectrum correction algorithms, this paper presents an improved double-windowing method, as well as the improved extended-precision FFT scheme for fixed-point DSP. The feasibilities of the two reformative methods are discussed theoretically, and the validities are testified by the simulation results.
