Quadrature-demodulation

获取Knn，即网络中邻接节点的度值。通过Knn可以知道，网络是同配还是异配(Access Knn, that is adjacent network node value. Through KNN can know the network is the same with or different allocation)

统及系统响应实验二用FFT作谱分析实验三用双线性变换法设计IIR数字滤波器(cessing lab report experiment a signal, system and system response for the second experiment with the FFT spectrum analysis experiment with three bilinear transform IIR digital filter design)

梯度下降（可视化,两个例子），对于初学者来说有用。(Gradient Descent（visualization，two examples）)

北斗卫星导航系统 空间信号接口控制文件，公开服务信号 B1I（1.0 版）(BeiDou Navigation Satellite System，BDS)

Spectral estimation（谱估计）的目标是基于一个有限的数据集合描述一个信号的功 率（在频率上的）分布。功率谱估计在很多场合下都是有用的，包括对宽带噪声湮没下的信 号的检测(Spectral estimation)

VC6.0通过matcom调用m文件的文章(VC6.0 m file by calling the article matcom)

The timing_recovery_1.mdl uses Simulinks variable step solver to create a continous time QPSK signal with both carrier and symbol rate errors. This is a relativly straight forward approach, but is computationally expensive. The sescond model, timing_recovery_2Q.mdl uses a purely discrete time approach using the same fractional sample delay approach as does the receiver. This can run much faster.

计算差分盒维数的matlab程序,是根据一篇文章写出来的，我也是下载的，看着不错就穿上来了，但还不知这样求维数对不对？(difference calculation of the box dimension Matlab procedure is based on an article written by, I also downloaded, Seeing good to wear it, but it has not requested such dimension that right?)
