说明: 4. 试说明卷积编解码的工作原理:
(1) 使用Simulink仿真卷积编码,并用Viterbi译码的方法进行解码,其中的编码、译码全部是自己编写代码(S-Function方式),不是调用Simulink的已有编码、译码函数。
(2) 请在加性白高斯噪声信道中,画出比特信噪比与误码率的关系曲线。(4. Try to explain the working principle of convolutional codec:
(1) Simulink was used to simulate convolutional coding, and Viterbi decoding method was used for decoding. The coding and decoding were all written by oneself (s-function method), rather than calling the existing coding and decoding functions of Simulink.
(2) in the additive white gaussian noise channel, please draw the curve of the relationship between bit signal-to-noise ratio and bit error rate.)

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)
