交错网格时间二阶空间十二阶声波方程数值模拟，加PML吸收边界，倾斜地层(Staggered grid space second-order time 12 order acoustic equation numerical simulation of the PML absorbing boundary, tilted strata)

复数计算，使用类来做的，可以选择自己要计算的方式(Complex calculation, using the class to do, and can choose their own way to calculate the)

双音多频，由高频群和低频群组成，高低频群各包含4个频率。一个高频信号和一个低频信号叠加组成一个组合信号，代表一个数字。DTMF信号有16个编码。利用DTMF信令可选择呼叫相应的对讲机。(Dual tone multi-frequency, high-frequency and low-frequency group composed of groups, high-frequency group contains four frequencies each. A high-frequency signal and a low frequency signal is superimposed to form a combined signal representative of a number. DTMF signal has a 16 code. DTMF signaling to the appropriate use of the intercom call.)

MIMO-OFDM channel estimation 。是基于mmse准则的，欢迎大家下载使用。(MIMO-OFDM channel estimation. Is based on the MMSE criteria, welcomed everyone download.)

滤波器的程序，是属于数字滤波器的，非常好好(Filter procedure, belongs to the digital filter, very good)

simulink一些应用实例和相关练习 很与参考价值(simulink some application examples and related exercises are with the reference value)

ISAR的成像程序，希望大家一起共享，谢谢了(ISAR imaging procedures in the hope to share with everyone, thank you)

实现智能编辑控制控件和一个滑杆控制控件可以同步变化(Editorial control Intelligent control and a slider control can take place in parallel changes in control)

Adaptive Thresholding by Variational Method

说明：  OFDM调制的的AWGN加瑞丽衰落信道，其它的我就不多说了(OFDM modulation of the AWGN Jiaruili fading channel, and others I do not talk a lot)
