- 通過(guò)對傳統的短時(shí)Fourier變換進(jìn)行改造,在短時(shí)Fourier變換的計算中利用自回歸(AR)譜估計代替離散Fourier變換(DFT),得到了一種基于A(yíng)R譜估計的短時(shí)AR譜分析方法.In the calculation of STFT, discrete Fourier transform (DFT) is replaced by autoregressive (AR) spectrum estimation, and a new method based on AR spectrum estimation is gained, namely short-time AR spectrum analysis.
