说明：  某炼厂常压塔实测数据和人工化验结果（汽油干点）。假设输入变量为常顶温度、顶回流温度、进料温度、进料压力、常顶压力共5个变量；输出量为汽油干点。试用BPNN建立此常压塔汽油干点软测量模型。(A certain refinery atmospheric column measured data and artificial test results (gasoline do). Assume that the input variables for the top temperature, reflux temperature, feed temperature, feed pressure, often a total of five variables Do some output for petrol. Trial BPNN the atmospheric column gasoline with some soft measurement model is established.)

说明：  首先，在非视距环境中，信号传播将产生多径效应，这将导致对到达时间的错误估计。其次PSO(Firstly, in NLOS environment, signal propagation will produce multipath effect, which will lead to wrong estimation of arrival time. Second, PSO)

说明：  压缩感知重构信号的实例 压缩感知（Compressed sensing），也被称为压缩采样（Compressive sampling）或稀疏采样（Sparse sampling），是一种寻找欠定线性系统的稀疏解的技术。(An example of compressed sensing reconstruction signal)

使用matlab 感知器工具箱函数newp编写单层感知器文件，模式识别作业(Use the matlab perception toolbox function newp the preparation of single-layer perceptron file, pattern recognition operations)

本程序实现了差分相移键控(DPSK)的调制与解调，得到了眼图。(This program simulates the Differential Phase Shift Keying(DPSK)system to obtain a eye diagram.)

说明：  基于LCL并网逆变器pq控制的matlab仿真(PQ control based on LCL grid-connected inverter)

地震数据时深转换，深度域的模型需要转换到时间域，方便与实际时间域的地震数据进行对比(When the depth conversion of seismic data, the model needs to be converted to the depth of field in time domain, convenience and seismic data to compare the actual time domain)

说明：  利用Matlab程序实现蝴蝶混沌效应，该例程形象直观的再现了数值分析有关原理(using Matlab program Chaos Butterfly Effect, the routine visual image of a replay of the numerical analysis of the principle)

HMM模型的MATLAB实现，HMM模型是语音识别方面一个重要的技术手段(HMM in MATLAB, HMM Speech Recognition is an important area of technical means)

定时恢复在接收机中是必不可少的环节，只有定时恢复环节性能良好才能正确解调出信号。 位同步-gardner算法(Timing recovery is an essential part of the receiver, and the signal is demodulated correctly only when the timing recovery is in good performance.)
