THIS FILE DESCRIBE THE CALCULATION OF BIT ERROR RATE (BER) OF A MODULATED SYSTEM AND THE PLOT OF THE BER WITH SIGNAL TO NOISE RATIO (SNR) TO EVALUATE THE SYSTEM BEHAVIOR

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.)

本文给出了m序列多项相关性的概念，还研究了生成多项式计数的问题(In this paper, the concept of multiple correlation m series, also studied the problem of generation polynomial count)

该代码为基于PID神经网络的系统控制算法(The code is a system control algorithm based on PID neural network)

MATPOWER是MATLAB的M文件包® 求解潮流和最优潮流问题。它的目的是作为一个研究者和教育者，是易于使用和修改仿真工具。MATPOWER是设计给最佳的性能，同时保持代码的简单理解和修改。它最初是为POWERWEB项目的一部分。(MATPOWER is a package of MATLAB® M-files for solving power flow and optimal power flow problems. It is intended as a simulation tool for researchers and educators that is easy to use and modify. MATPOWER is designed to give the best performance possible while keeping the code simple to understand and modify. It was initially developed as part of the PowerWeb project. )
