HMT

This code calculate the Qam modulation for a network communication

产生PRN32颗卫星的CAcode，并求自相关(Geneter CA codes of PRN32 satellites)

说明：  图像处理代码，能够对一张RGB图像类型的图片进行裁减，并且二值化处理。(Image processing code, capable of an RGB image types of pictures cut, and the binary treatment.)

Sparse Bayesian Learning

说明：  此程序为语音信号的过零率检测，白噪声过零率远远高于语音信号，故可通过对过零率的检测判断出是不是语音信号。(This procedure for the zero rate of speech signal detection, white noise zero crossing rate is much higher than the speech signal, it can zero rate by detection of voice signal is not judged.)

ML法能够很好的估计信号的信噪比,DC-DC部分采用定功率单环控制，代码里有很完整的注释和解释。( ML estimation method can be a good signal to noise ratio, DC-DC power single-part set-loop control, Code, there are very complete notes and explanation.)

测绘工程中常用的坐标转换代码，有WGS-xyz坐标系转经纬度、ENU坐标，有北天东坐标系转WGS-xyz、经纬度等(MAPPING commonly used coordinate transformation code, WGS-xyz coordinate system of latitude and longitude turn, ENU coordinate with the northern east coordinates turn WGS-xyz, latitude and longitude)

programming for Omni-directional image. they are useful for novice.

说明：  三自由度 3-DOF 平台的运动学和轨迹规划(Kinematics and Trajectory planning of a 3-DOF platform with 3 extensible limbs)

说明：  正交信号校正，一种预处理算法，用来消除光谱中与浓度无关的信息，增强浓度与光谱的相关性(Orthogonal signal correction, a preprocessing algorithm, to eliminate the information in the spectrum unreleated with the target concentration, enhanceing the correlation between concentration and spectral )
