MATLAB中常用的程序
- MATLAB中常用的程序,包括硬阀值、软阀值、全局阀值,小包波去噪等等,希望对初学者有用。,Procedures commonly used in MATLAB, including the hard threshold and soft threshold, global threshold, wave packet de-noising, etc., in the hope that useful for beginners.
MSK
- 最小频移键控(Minimum Shift Keying,MSK)是一种具有连续相位和最小频偏的数字调制技术。MSK的突出优点是信号具有恒定的包络和信号的相位连续性,频带利用率高,信号的功率谱在主瓣外衰减较快,这就使得它对邻波道干扰小。-MSK (Minimum Shift Keying) is a continuous phase and the minimum deviation of the digital modulation techniques. Outstanding advanta

package_emd
- 经验模态分解(Empirical Mode Decomposition,EMD)法是黄锷(N. E. Huang)在美国国家宇航局与其他人于1998年创造性地提出的一种新型自适应信号时频处理方法,特别适用于非线性非平稳信号的分析处理。对经过EMD处理的信号再进行希尔伯特变换,就组成了大名鼎鼎的“希尔伯特—黄变换”(HHT)。由于脑电信号处理很少在EMD之后接上希尔伯特变换,在这里仅介绍EMD的相关基础知识。 EMD其实就是一种对信号进行分解的方法,与傅里叶变换、小波变换的核心思想一致,大家
