quadrature_sampling

viterbi译码，利用matlab进行的仿真平台搭建(viterbi decoding, the use of matlab simulation platform built for)

说明：  复杂网络中的GN算法...............(Complex network of GN algorithm ...............)

用MATLAB实现最小二乘法和最小方差的参数辨识(Using MATLAB complete parameter identification method of least squares and minimum variance)

here is the code for serial communications

此代码只要是自然梯度算法（naturalness_gradident_arithmetic，使用matlab编写的，一起学习(This code as long as it is the natural gradient algorithm (naturalness_gradident_arithmetic, using matlab prepared to learn)

三维重构计算空间距离，在图像匹配后计算得到。(Three-dimensional reconstruction calculated distance, the images calculated after matching.)

用matlab实现基2时间抽取快速傅里叶变换fft(Base 2 with matlab time taken to achieve the fast Fourier transform fft)

说明：  这个程序是用MATLAB编写得一个灰度共生矩阵特征及其一些参数得计算，希望对大家有用。(The MATLAB program is written, a GLCM features and some of the parameters was calculated, and I hope useful.)

Viterbi decoding for communication

利用burge算法估计功率谱，并画出不同参数情况下的功率谱曲线。。希望对大家有帮助。(burge algorithm)
