At the same time, based on the knowledge of digital signal processing, reconstruction by harmonic correction and timevariant digital filter was proposed.
与此同时,结合数字信号处理知识,分别用谐波修正和时变数字滤波器的方法,完成基于骨导信号的语音重构。

All the data used in analysis and process is collected in different time. The result shows that sea clutter is slow timevariant and can be corrected by adaptive processing.
Experiments show that the multiresolution analysis of wavelet transform is an effective new method for processing unstable signals having timevariant spectra.
