线性调频雷达信号的生成，观察其实部虚部，还有延时。以及脉冲压缩 经过匹配滤波器之后的的波形(the generator of the lfm。see the real part and the not real part。 at last though the match filter.)

基于ＰＩＤ的性能监测与评估技术，但是是单个ＰＩＤ的．多回路的暂时没有找到．(PID-based performance monitoring and assessment techniques, but it is of a single PID. Multi-loop did not find the time being.)

在MATLAB环境下实现参数估计的傻瓜式操作(Implementation in MATLAB environment parameter estimation operation of a fool)

matlab求解二阶常微分方程数值解，具有较好的效果，对学习matlab非常有用。(matlab solving second order ordinary differential equations, with good results, to learn matlab very useful.)

该程序用以对m序列码的调制在负dB情况下解调的仿真，是对基带信号的调制(procedures for the right sequence code m in the negative dB modulation of the demodulation simulation of the base band signal modulation)

OFDM is one of the best physical-layer candidates for cognitive radio (CR) systems, but rectangular pulse shaping gives rise to large spectrum sidelobes and interferes with the licensed user on the adjacent band. In this paper, an approach is derived based on the signal continuity to measure the spectral decay rate of the shaping pulse for OFDM.

根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)
