此程序为基于CAR的递推最小二乘算法，使用语系统辨识的初学者(This procedure is based on the CAR of the recursive least squares algorithm, using the language of system identification for beginners)

基于matlab的数字基带系统各种调制解调链路，包括am,ssb,pcm等，对调制信号，误码率，眼图等进行了仿真(Matlab-based system, a variety of digital baseband modem link, including am, ssb, pcm, etc., on the modulation signal, the error rate, eye diagrams simulated)

This paper is based on artificial neural network. artifivial neural network is a patter recognition mechanism that resembles the human brain. It have input layers, hidden layers and output layers. ANN provides beter recognition accuracy than other classifiers.

电力系统加权最小二乘法状态估计14节点或33节点都能运行(Weighted least square method for power system state estimation of 14 nodes or 33 nodes can run)

说明：  求解方阵所有的特征值以及特征值对应的特征向量(all eigenvalue and the corresponding eigenvectors for square matrix)

电力系统优化，按照等微增率原则分配该发电厂24小时的负荷(Power System Optimization)

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)

说明：  课程设计上用matlab编写的16qam的译码，很好用的.m文件。(Curriculum design 16qam written with matlab decoding, the good. M file. )
