filtering and salt and pepper noise reduction

用于信道估计的LS算法仿真 我们对基于信道估计的训练序列进行了一个详细的研究，此种训练序列是用在中继节点的转接放大设计上。(we provide a complete study on the training based channel estimation issues for relay networks that employ the amplify-and-forward (AF) transmission scheme.)

计算golden sequence的自相关，ACF_of_PN_Sequence(ACF_of_PN_Sequence)

归一化LMS算法，自己更改参考信号和期望信号(normalized LMS algorithm，change the reference signal and desired signal by yourself)

matlab中解调谱的示例程序，操作简单，可直接复制，便于调用。(spectrum demodulation in matlab sample program, simple operation, can be directly copied, easy call.)

用 MATLAB实现直方图阈值法,对分析概率分布有比较好的描述(Using MATLAB histogram method, the analysis of the probability distribution has a better description)

plot the psk curves .Useful for the beginners.

Turbo编译码程序，内含注释；信道编码经典程序 内含3GPP、LTE标准，已验证正确，适合学习(Turbo encode and decode, containing comments channel coding classic program Containing 3GPP, LTE standards, verified correctly for learning)

生物模型数值仿真，预测种群数量大小，模拟平衡态的稳定性(Numerical simulation of the biological model, to predict the size of the population, to simulate the stability of the equilibrium)

matlab代码实现一个快速时钟恢复的代码，这里可以看到一个具体的clock and data recovery的例子(it is about clock and data recovery，is a very useful tools to simulate the problems in communication!)
