说明：  高斯白噪声无线通信信道下的误码率仿真，希望对你的学习有用(Gaussian white noise of wireless communication channel under BER simulation, you would like to learn useful)

信号估计仿真，线性最小误差估计的仿真。《随机数字信号处理》的实验与实践教学部分(Signal estimation simulation, simulation of linear minimum error estimation)

The subroutines glkern.f and lokern.f use an efficient and fast algorithm for automatically adaptive nonparametric regression estimation with a kernel method. Roughly speaking, the method performs a local averaging of the observations when estimating the regression function. Analogously, one can estimate derivatives of small order of the regression function.

雷达信号的模糊函数Matlab代码，包括线性调频信号，线性调频脉冲串信号，以及作为对照的单频信号。通过比较分析可以得到不同信号的模糊函数表现出的不同特征。(Radar chirp signal ambiguity function Matlab code, including linear FM signal, the chirp pulse train signal, as well as the control of the single-frequency signal.)

说明：  目标跟踪问题的应用背景是雷达数据处理，即雷达在搜索到目标并记录目标的位置数据，对测量到的目标位置数据（称为点迹）进行处理，自动形成航迹，并对目标在下一时 刻的位置进行预测。本文简要讨论了用Kalman滤波方法对单个目标航迹进行预测，并借助于Matlab仿真工具，对实验的效果进行评估。 (kalman filter)

说明：  离散数据的快速傅里叶变换。读取一段数值模拟得到的时间历程曲线，进行fft变换，得到幅频曲线。(Fast Fourier transform of the discrete data. Read the section of numerical simulation of the time course of the curve, fft transform, the amplitude-frequency curve.)
