主要介绍了基于（单、多）高斯统计模型的背景获取法(Mainly based on the (single, multi-) Gaussian statistical model to obtain the background of law)

skyline method to inverse K matrix in [K]{X}={F}

此程序为信号阶次分析，主要针对汽车上振动噪声信号(Order this program for signal analysis, the main noise and vibration signals for the car)

matlab的图像分割代码，很详细的注释，相信大家会有用的。(matlab image segmentation code, very detailed notes, I believe we will have to use.)

基于MATLAB simulink 的QPSK仿真，R2008下测试可运行。提供波形、频谱、眼图、星座图。(Based on MATLAB simulink simulation of QPSK, R2008 under test can be run. It provides waveform, spectrum, eye diagrams, constellations.)

实现了雷达跟踪算法里的EKF滤波算法，统计了跟踪误差。(Radar tracking algorithm of the EKF filter algorithm, statistical tracking error.)

用viterbi算法和baum-welch训练找到和更新best path(find best path using Viterbi algorithm and Baum-Welch training)

Hurst数计算，用于算法交易，非常有用(Hurst index)

产生两不迥频率的信号，并对两信号作复数FFT变换，找出频率为50Hz的信号对其进行能量计算(Two distant signal is not generated frequency, and two signals for complex FFT transform to identify the frequency of 50Hz signal to calculate its energy)

一阶QKF（积分卡尔曼滤波）算法，性能优于UKF、EKF，谢谢~(An order QKF (integral Kalman filter) algorithm outperforms UKF, EKF, thank you ~)
