说明：  基于UPML吸收边界的三维FDTD数值模拟程序(3-D FDTD code with UPML)

二维FDTD程序，采用Mur吸收边界，实现了较好的吸收效果，可以用来与UPML吸收边界比较。(2D FDTD program, the Mur absorbing boundary to achieve a better absorption, can be used with UPML absorbing boundary.)

说明：  单极性脉冲调制方式，三角载波在一种极性内变化(Unipolar pulse modulation, triangular carrier changing in one polarity)

this is simmulation 16-qam modulation in rayleigh channel

说明：  杂波模型，可用于雷达信号处理中，其中模型为瑞利分布(Clutter model can be used for radar signal processing, which for the Rayleigh distribution model)

处理nc文件，生成grads用的ctl文件和数据(deal with netcdf file,and output the ctl file and data for the Grads software！)

WIND FRAM CONNECTED WITH GRID

一端关于数字化信道接收机的源码，作毕设时用的，希望对大家有用(end of the digital channel receiver source for complete use of the established, we want to help! !)

说明：  计算了内燃机的压缩过程，并显示缸压-曲轴转角，温度-曲轴转角曲线图(The compression process of internal combustion engine is calculated and the curves of cylinder pressure-crank Angle and temperature-crank Angle are shown.)
