提出了一种改进的积分梳状(CIC) 滤波器. 在改变传统积分梳状滤波器的延迟因子的 同时,将锐化(Sharpen) 技术和相位分解技术应用于此滤波器. 改进后的滤波器与传统滤波器 相比,减少了信号失真,降低了系统功率消耗. 仿真结果表明,改进后的滤波器在通带范围内的 波动很少,而且,具有较高的阻带衰减.(An improved Integrator Comb (CIC) filter. In changing the traditional integral comb filter delay factor, we will Sharpen (Sharpen) technology and phase decomposition technique used in this filter. Improved filtering Compared with the traditional filter device to reduce the signal distortion and reduces system power consumption. The simulation results show that the improved pass-band filter in the framework of the volatility of small and with high stopband attenuation.)

扩频通信系统仿真 ——系统将基带信号（即信息）的频谱扩展至很宽的频带上，然后再进行传输，即将欲传输的信息数据用伪随机序列编码调制，实现频谱扩展，然后通过信道编码发送出去；接收端采用与发送端完全相同的伪随机序列作为本地解扩信号进行相关处理，以恢复信息，最后进行解调，完成整个系统的接收。(Simulation of spread spectrum communication system- the system baseband signal (ie, information) be extended to a wide spectrum of frequency bands, and then transferred, will want to use transmitted information data sequence of pseudo-random code modulation, to achieve expansion of the spectrum, and then sent channel coding receiver and transmitter use the same pseudo-random sequence as related to the local despreading signal processing, in order to restore the information, the final demodulation, the receiver to complete the system.)

说明：  信号的DFT和FFT频谱分析，以及对乃奎斯特采样频率的理解练习，对信号分析的朋友很有帮助( For a Linear Frequency Modulation signal,try to analyze its property in frequency domain.Given a system h(t) output.)

语音发音动作，画唇和舌头的正面侧面图的matlab程序。(draw the picture of lip and tongue.)

说明：  用蚁群算法解决VRP问题，包含基本蚁群算法（我记得不含时间窗约束）(Using ant colony algorithm to solve VRP problem, including basic ant colony algorithm)

指纹识别的matlab程序，里面包括了一些指纹图片，利用gabor小波进行识别(Fingerprint recognition matlab program, which includes a number of fingerprint images using gabor wavelets to identify)

K-means is a clustering algorithm In the beginning we determine number of cluster K and we assume the centroid or center of these clusters. We can take any random objects as the initial centroids or the first K objects in sequence can also serve as the initial centroids. There are two function for that the kMeanCluster and distMatrix

说明：  车牌定位的源代码，通过颜色特征过滤抽取将黄色区域抽取出来(plates positioning of the source code, color filter characteristics will be collected yellow regional extracted)

以MATcom为内核的C++程序，调用MATLAB拟合衰减振荡曲线（多线程）(In MATcom as the core C++ program, call the MATLAB fitting damped oscillation curve (multi-threading))

说明：  Train speed/time moving wheel load
