程序
说明: 1、基带码型仿真
(1)通过仿真观察占空比为50%、 75%以及100%的单、
双极性归零码波形以及其功率谱,分析不同占空比对
仿真结果的影响。
(2) 通过仿真产生一随机消息码序列,将其分别转换为
AMI码和HDB3码,观察它们的波形及其功率谱密度。
2、数字带通调制系统仿真
设计一个采用2ASK( OOK) 调制的数字通信系统:
产生二进制随机数据,并仿真其对应的2ASK调制波形,
分析其频谱。所产生的调制波形加入不同信噪比的白噪声,
选取合适的接收方案,画出系统误码率曲线,并与理论误
码率进行对比。(1.Baseband pattern simulation
2. Simulation of digital band-pass modulation system)
