QAM
编写一个含QAM传输的发送和接收模块
1)分别采用复基带仿真和实带通仿真两种形式
a) 实带通仿真时, 载波频率为符号率的4倍
b)发端采用滚降系数0.5的根号升余弦滤波器
2)画出Eb/N0=15dB时的接收波形(收滤波前),取100个采样
3)画出发端输出的眼图和收端过匹配滤波后的眼图(画眼图时不加噪声)
统计误符号率和误比特率与Eb/N0的关系,画出曲线, 与理论计算的曲线相对比
(Prepare to send of one with QAM transmission and receiver module 1), respectively, the complex baseband simulation and the real band-pass simulation in two forms a) the real band-pass simulation, the carrier frequency used for the symbol rate of 4 times b) the originator roll-off factor of 0.5 root raised cosine filter, 2) draw Eb/N0 = 15dB when the received waveform (closing filter), take 100 samples) to draw the originator of the output eye diagram and income side of the eye diagram after the matched filter ( draw the eye diagram without noise) statistics symbol error rate and bit error rate and Eb/N0, draw a curve calculated with the theoretical curve compared)

CTBXZ
动态电力系统次同步谐振.次同步谐振一是交流输电系统中由串联电容补偿引起的次同步谐振问题，二是由一些电气装置引起的次同步振荡问题。次同步振荡会使轴系产生很大的扭矩，严重情况下可能导致大轴出现裂纹甚至断裂， 或因反复承受较大转矩造成疲劳积累， 使轴系寿命降低。因此，对次同步振荡进行准确的分析和计算， 采取有效的监视、防止和保护措施是非常重要的。程序是对交流线路串补偿电容引起的次同步振荡抑制的编程。(dynamic power system subsynchronous resonance.)
