The newly emerged JTFA (Joint Time-Frequency Analysis) method is a powerful tool in analyzing time-varying non-stationarysignals.
近年来才兴起的时-频联合分析法是分析处理频率随时间而改变的非稳态信号的强有力工具。

The algorithm of local projective nonlinear noise reduction based on nonlinear dynamic system is more effective for noise reduction of chaotic signal and non-stationarysignals.
基于动力系统模型的局部投影非线性降噪算法，对混沌信号和一大类非平稳信号具有明显的降噪效果。
