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)
