利用burg和Levinson-Durbin算法，根据100年间每年12个月记录到的太阳黑子出现次数的平均值求太阳黑子的活动周期(Burg and the use of Levinson-Durbin algorithm, according to 100 years, 12 months a year recorded the average number of sunspots appear for the activities of sunspot cycle)

说明：  对于MATLAB，许多人无从下手，这是一个学习源码！(Regarding MATLAB, many people start without knowing where to begin, this is a study sound code! )

adc converter, sampling and cuantization code

仿真锁相环系统，可以仿真锁定时间。不同的环路带宽对系统的非理想特性！(PLL simulation system that can lock simulation time. Different loop bandwidth of the system of non-ideal characteristics!)

该程序是用matlab语言实现的对瑞利信道的描述，读者可以一试(The program is described by Rayleigh channel matlab language, readers can try)
