说明：  matlab .M函数库，自己整理的，我用的很好，朋友们能参考一下(matlab. M library, his finishing, I use the good friends who can refer to)

本文提出了一种适用于低轨卫异扩频通信系统的多普勒频移快捕方法.该方法基于数字匹配滤波器及自动频率控制环路_利用数字匹配滤波器的囚码快捕特性及其输出主相关峰值对频偏的敏感性，缩短多普勒频移的 捕获时间.论文首先推导了多普勒频移的平均捕获时间表达式，然后根据数值分析结果得到了准最佳捕获判决策略，最后通过比较验证了该快捕方法相对于传统串行捕获方法在性能上的提高. (This paper presents a low-orbit health for different spread spectrum communication system fast catching the Doppler shift method, which based on digital matched filter and automatic frequency control loop _ prisoners using digital matched filter code features rapid acquisition and the output of the main correlation peak frequency deviation of the sensitivity of the Doppler frequency shift to shorten acquisition time. paper first derive the mean Doppler shift acquisition time expression, then the numerical results obtained quasi-optimal capture decision strategies, and finally verified by comparing with the rapid acquisition method to capture the traditional method of serial improvement in performance.)

说明：  灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system.)

说明：  利用Matlab实现子功率谱的求解，并实现信号处理和能量算法(Matlab, the solution to achieve sub-power spectrum, and algorithms for signal processing and energy)

应用Benders分解算法求解混合0-1规划。对于研究非线性规划的同学很有益。(Application Benders decomposition algorithm for mixed 0-1 programming. Very useful for the study of nonlinear programming students.)
