this is some codes in systems

北斗二代B1频点接收机主程序Matlab源代码(BD2B1 Matalab Receiver)

Hata pathloss model matlab implementation.

语音信号处理的端点检测程序，在编程中调用，很实用，值得你一看。(Endpoint detection)

图像的拉普拉斯变换及其matlab代码实现及代码测试(Images of the Laplace transform and its matlab code implementation and testing )

2代小波示意程序-此程序用提升法实现第二代小波变换-我用的是非整数阶小波变换-采用时域实现,步骤先列后行(2 Generation Wavelet indicated procedures- This procedure is used to upgrade method second generation wavelet transform- I use a non-integer order wavelet transform- time-domain implementation steps first column underwent)

surf算法，实现特征点检测和匹配.文件内有两个图像匹配实例(surf algorithm, feature point detection and matching)

Matlab PCA主成分分析 一个比较好的matlab代码，非常有用(Matlab PCA PCA matlab code is a relatively good, very useful)

轨迹发生器,自动生成导航轨迹,可用于导航解算。(Trajectory generator, automatically generate the navigation path can be used in navigation solution)

使用每秒10个采样的频率 ，对信号 进行采样，画出原始信号的傅立叶变换X(f) 和理想采样信号的傅立叶变换 。假定重构滤波器是带宽为 的理想低通滤波器，具有带通增益 ，画出重构滤波器的输出(Using 10 samples per second frequency, the signal is sampled, to draw the original signal Fourier transform X (f) and the ideal sampling signal Fourier transform. Reconstruction filter is assumed that the ideal bandwidth low-pass filter with a bandpass gain, draw the output of reconstruction filter)
