通信编码
说明: lbc_example:未编码的BPSK调制的性能(理论计算与仿真)、重复码硬判决的性能
lbc_example_SD: 未编码的BPSK调制的性能(理论计算)、重复码硬判决的性能、重复码软判决的性能
lbc_example_SD_EbNo:lbc_example_SD中的性能,并且进一步考虑了码率不同时,对于信道的SNR值进行归一化,以Eb/No = SNR/(2*R)为横坐标时的比较结果
lbc_example_Hamming_EbNo:汉明码,硬判决译码的性能(Lbc_example: Performance of uncoded BPSK modulation (theoretical calculation and simulation), performance of duplicate code hard decision
Lbc_example_SD: Performance of uncoded BPSK modulation (theoretical calculation), performance of hard decision of duplicate code, performance of soft decision of duplicate code
The performance of lbc_example_SD_EbNo: lbc_example_SD is considered, and the SNR value of channel is normalized when the bit rate is different. The comparison results are obtained when Eb/No = SNR/(2*R) is the abscissa coordinate.

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
