RELAX算法，参数化谱估计（线谱）_RELAX方法(RELAX algorithm, parametric spectral estimation (line spectrum) _RELAX method)

communication modulation technique code

用MATLAB运行主成分，可以求出特征向量，等非常实用。(MATLAB operation principal component, can work out characteristic vector, and very practical. )

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.)

本压缩文件包括对线性量级，对数量级和指数量级三种AGC方案的仿真，并包括msk信号通过agc回路的一个仿真文件，附带详细的仿真报告(this zip file includes 3 matlab file simulating 3 agc method（linear，log，and exponential).In addition, this file includes an simulation file of msk signal passing through agc loop.An simulation paper is included, too.)

This is a method called Metoda Fibonacci. And with this method you can find the the optimum way.
