16qam_channel_encode
一、 本程序采用16QAM调制方式,对一串2进制信源进行调制,采用(7,4)循环码对信源做信道编码,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,再对信号进行信道解码,画出采用信道编码技术和不采用信道编码技术的误比特率图。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated, using (7,4) cyclic code of the source-channel coding to do with a raised cosine roll-off function for base-band modulation, and then transferred to a 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, and then right channel signals, decoding, channel coding techniques used to draw and non- channel coding techniques using bit error rate plans.)

RCPCED
仿真程序主体部分由c语言完成,改变运行的设定的参数,在相同的信道编码速率下,通过改变误码率,用Matlab软件进行画图,得出在相同编码速率不同误码率下的纠错后误码的比率,接着改变编码速率,重新可以划出另外的两条曲线;(simulation program from the main part of the completion c language, change the operation of the set parameters, the same channel coding rate, by changing the error rate using Matlab software for drawing, reached the same rate of different coding error rate after correction of the error rate, and then change the coding rate, can be re-drawn the other two curves;)

GP in power system
利用遗传程序设计建立电力系统的负荷模型,无需像传统方法一样预先确定具体的模型结构,它能根据输入输出数据直接演化出变量间的函数关系,并且能够一次性的同时确定函数的结构形式和参数,使得模型的生成过程趋于智能化、自动化,解决了负荷建模工作中长期困扰的模型辨识问题。(Genetic Programming(GP) is a new evolutionary algorithm based on genetic algorithm,which has self-adaptive,self-organizing,self-learing and other advantages.As a kind of automatic programming technology,it tries to study the computer how to solve the problem according to the objective enviroment automatically without human intervention.)
