经典载波跟踪环costas环simulink建模仿真，采用QPSK调制，包含上下变频以及三种不同鉴相方式。(Classic costas loop carrier tracking loop simulink modeling and simulation, using QPSK modulation, including the upper and lower frequency, as well as phase three different ways.)

这是一个接收机解映射程序，可供无线通信仿真的朋友参考(This is demapping program)

RIMM与IMM的程序比较，就是两中方法比较哪个跟踪效果比较好(RIMM IMM with the procedure, which is two methods which track the results were quite good)

AR模型的Yule-Walker方程.1927年，Yule提出用线性回归方程来模拟一个时间序列。Yule的工作实际上成了现代谱估计中最重要的方法——参数模型法谱估计的基础。Walker利用Yule的分析方法研究了衰减正弦时间序列，得出Yule-Walker方程，可以说，Yule和Walker都是开拓自回归模型的先锋。(The Higher-Order Yule-Walker method.)

时间混叠算法进行循环谱估计，信号为fsk(ta，fsk)
