Matlab色差公式，含CIE DE2000、CIE94、CIEanlab(Matlab color difference formulas containing CIE DE2000, CIE94, CIEanlab)

本程序是关于卫星上下变频的简单的实现算法，首先产生双边带调制信号，与收本振混频后，通过低通滤波器完成下变频。再与发本振混频，通过高通滤波器后完成上变频(This program is a simple algorithm on the satellite and down-conversion, the first double-sideband modulation signal generated, after the close of the oscillator mixer, low-pass filter complete the conversion. Again and send the local oscillator mixer, followed by the completion of the high-pass filter frequency)

有关于时延估计方法的总结，包括广义相关分析法的应用及方法的改进等，非常有帮助。(About time delay estimation method , including the application of generalized correlation analysis method and the improvement methods and so on, which are very helpful.)

说明：  hopfield分类，功能强大，比较不错，建议下载( divide ，can use it to divide the thing you want)
