  • SBOCCrare
    几个BOC 信号的分析例程,全球卫星导航系统将普遍使用BOC调制信号作为扩频测距信号,BOC信号号自相关函数呈现多个相关峰,传统扩频接收机所用的延迟锁定环(DLL)无法对该信号正确地进行码相位的 (Several BOC signal analysis routines, the global satellite navigation system will generally use the BOC modulation signal as a spread spectrum ranging signal, BOC signal autocorrelation function presents multiple correlation peaks, the traditional spread spectrum receiver with the delay locked loop (DLL ) can not be the signal code phase)

  • predict-and-match-interal-multiple
    地震信号处理,虚同相轴方法预测层间多次波,将数据分成上下两部分,利用相关和褶积的原理预测出层间多次波。预测信号和原始信号在相位和振幅上存在差异,用L1范数匹配法进行匹配,其中,提供了两种方法解病态方程,分别为高斯-赛德尔方法和正则化方法。(Seismic signal processing, predicte internal multiples by construct virtual events .The data is divided into two parts, using the principle of correlation and convolution to predicte multiples. There are differences between the prediction signal and the original signal on the phase and amplitude, so we use the L1 norm method to match the singal.We provide two methods for solving ill equation, respectively Gauss- Seidel method and regularization method.)

  • HHT
    目前,互联网上HHT信号处理技术有 三种实现方式,采用MATLAB编程语言,一种是法国研究者设计的G Rilling 2007 另一种是MATLAB文件交换中心由Alan Tan开发的plot_hht程序包,第三种是台湾中央大学数据研究中心提供的EEMD包。 其中,我使用了plot_hht程序包,其使用了三个终止条件,驻留分量的单调性,极值点与零点的个数相差不超过1,还有黄锷1998经典文献提出的 SD>0.1,单调性的判断,并不是去判定驻留分量是否是单调函数,而是当曲线是双曲线时,循环结束,由于没有考虑端点效应,程序比较简洁,好读懂,大家 学习HHT可以从这个程序包入手,在此抛砖引玉,希冀有人能比较这三种不同的算法的性能和时间复杂度,以及对各种信号的适应性。 (There provides three types of HTT program packages: one developed by France researcher G. Rilling 2007, the other provided by by Alan Tan from Matlab file exchange center and the third one by Taiwan Central University Data Research Center. Please start from the simple one by Tan to learn more.)
