说明：  从HFSS中提取S21，S11参数，获取相对磁导率和介电常数(Extraction S21, S11 parameters HFSS, gets relative permeability and permittivity)

计算电磁学中FDTD（有限时域差分法）三维的算法程序。(FDTD (finite difference time domain method) three-dimensional algorithm program in computational electromagnetics.)

matlab编程实现从东北天坐标系到地心坐标系的坐标转换，包含了资料文件。调用函数名为：ENVtoECEF，输入参数为东北天原点经纬度数据，东北天坐标点数据；输出数据是东北天坐标系下坐标点对应的经纬高数据。(matlab programming from the northeast sky coordinate system to the geocentric coordinate system conversion, including the data file. Call the function named: ENVtoECEF, input parameters for the origin of latitude and longitude data northeastern days, Northeast day coordinate data output data is northeast days coordinates of latitude and longitude coordinates of points corresponding to the high data.)

用ICA方法分离出脉搏波信号中的运动干扰信号，已经调试通过(ICA to isolate the the movement interference signal pulse wave signal, debugging has been passed)

主要用于对含有噪声的信号进行降噪处理，先小波包降噪再奇异值降噪(It is mainly used to denoise the signal containing noise. First, the wavelet packet de-noising and then the singular value denoising)

这个程序实现了基于OFDM系统的信道估计DFT算法的实现(This application implements the DFT channel estimation algorithm based on OFDM system implementation )

以二体问题为模型，从地球发射航天器探索火星，途中需经过一次无动力金星借力，寻找最优（总速度增量最小）的发射时间窗口和飞行时间，并绘制地球到金星的Pork-Chop发射能量等高线图。发射时间窗口为2023—2033年，总飞行时间不得大于2年。(Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.)

LLC仿真 自己搭的可以运行， 但不是变频闭环控制，是开环定频的(LLC simulation can run itself, but not frequency conversion closed loop control, it is open-loop constant frequency.)

针对LDPC码在理论和实现两方面分别进行了较深的研究。深入了解了LDPC码编码方法、译码方法以及性能等知识，重点研究了用MATLAB如何构造奇偶校验矩阵、如何编码和如何解码的算法，而且实现了在相同码率、信噪比下LDPC码性能与卷积码性能的对比。(LDPC codes for both theory and implementation were carried out deeper study. In-depth understanding of the LDPC coding method, decoding method and performance of such knowledge, focuses on how to use MATLAB parity check matrix structure, how to encode and decode algorithms how, but also achieved at the same rate, SNR LDPC codes Comparative performance and convolution code performance.)

matlab的gcv函数，可以用于求取正则化参数。是regtools工具箱中的(The gcv matlab function that can be used to strike the regularization parameter. Is regtools Toolbox)
