搭建了一个OFDM系统，并用基于导频的方式进行了信道的估计，最后画出了系统在3条径下的瑞利信道时误比特率随信噪比的变化。(bulid a OFDM system,make channel estimation based on pilot signal,finally,plot ber when SNR changed)

说明：  跳频通信仿真论文，大家看一下啊，好不容易找到的(Frequency-hopping communication simulation paper, we look at, ah, hard-won)

dear sir i have uploaded a few programs for your consideration

lms是重要的数字预失真系统，一种自适应算法(lms is important digital pre-distortion system, an adaptive algorithm)

采用GARDNER算法的定时模块的仿真，输入每个符号4个采样点，通过内插，输出一个样本值(GARDNER algorithm used the timing of the simulation module, enter each symbol four sampling points, by interpolation, the output value of one sample)

用matlab语言编写，实现分段函数的绘制，已经经过调试(Matlab language used to achieve sub-function mapping, has been commissioning)

说明：  基于matlab语言的针对33节点电力系统的电压初始值程序(Based on matlab language for 33 node power system voltage initial value program )
