simulation of QPSK over noise and rayliegh channel and compared with theoretical results

说明：  特征值的提取方式 有需要的可以下载试试 还不错(for the value )

MATLAB遗传算法源程序(MATLAB genetic algorithm source code)

对要发送的序列进行上变频，上变频到21MHz后进行发送。(change the frequence uop to the one that suit for transmission,which here is 21MHz.)

在MATLAB中实现用高斯消元法求解线性方程组!(In MATLAB to achieve using Gaussian elimination method for solving linear equations!)

DSP CODE FOR SIMULATION PROJECT IIR FILTER

本程序利用平方环实现载波同步，使用锁相环进行跟踪相位偏移(This program makes use of the square ring to achieve carrier synchronization, with the use of PLL to track the phase shift)

用matlab实现的BP神经网络，比较基础，对已有的语音信号进行分类，留了500个作为检验(Using matlab to achieve the BP neural network basis of comparison, the existing classification of the speech signal, leaving a 500 as a test)

This handbook is intended for anyone who wants a comprehensive survey of Fortran 90, including those familiar with programming language concepts but unfamiliar with Fortran. Experienced Fortran 77 programmers will be able to use this volume to assimilate quickly those features in Fortran 90 that are not in Fortran 77 (Fortran 90 is a superset of Fortran 77).

说明：  本书从MATLAB 仿真角度系统地介绍了PID 控制的基本理论、基本方法和应用技术，(MATLAB simulation of this book from the perspective of systematically introduced the basic theory of PID control, the basic method and application of technology,)
