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.
Lbc_example_Hamming_EbNo: Hamming Code, Performance of Hard Decision Decoding)
