此为我老师写的RGELS算法，适合系统辨识的初学者(This is my teacher wrote RGELS algorithm, suitable for system identification of the beginners)

简化的频域反馈判决反馈均衡器，系数不需要每次都更新。(simplified frequency decision feedback filter ，do not need to update factor everytime)

用MATLAB描写交互式多模型跟踪算法，包含算法和实际例子计算(MATLAB describes interactive multiple model tracking algorithm, including algorithms and practical examples of calculation)

LS信道估计算法仿真MATLAB,ls信道估计算法代码(LS channel estimation algorithm simulation MATLAB)

这是进行IGA分析的 Matlab代码.可用于进行1维，2维和三维的线弹性问题分析，并可以进行裂纹的扩展，夹杂等的计算。同时，包括Eular梁和Kirchhoff板在内的结构力学问题也可行。 (This is the the Isogeometric Analysis (IGA) Matlab code. The code supports one, two and three dimensional linear elasticity problems. Extended IGA for hole, inclusion and crack modelling is also implemented. Structural mechanics problems including Euler beam and Kirchhoff plates (rotation-free formulations) are implemented as well.)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, the program uses 16QAM modulation, the source of a string of two binary modulation, with the Raised Cosine modulated baseband functions, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter demodulation, demodulation constellation plot using the minimum Euclidean distance decoding decision, bit error rate calculation.)

采用Matlab编写的弹道分析算法，该算法可以模拟弹道飞行轨迹(Matlab preparation of the trajectory analysis algorithm, which can be simulated ballistic trajectory)

说明：  后联平滑滤波器的卡尔曼滤波器的使用，这个代码很不错的哦(After the joint smoothing filter is the use of the Kalman filter, this code is very good Oh)

直接扩频信号抑制正弦干扰效果，横坐标为信噪比，纵坐标为误码率(restrain of sinusoidal interference in ds_ss signal)

对于四分量高斯调制信号，比较STFT、WVD、CWD分辨率和交叉干扰情况(For the four component Gauss modulated signal, the STFT, WVD, CWD resolution and cross interference are compared)
