研究了基于Gold序列的地址码的生成,对其相关性、频谱效率进行分析,并且与光正交码、素数码的性能进行比较。分析结果表明:Gold序列是一种自相关和互相关性能比较好的码字,并且具有较大的码字容量,在相同参数下具有较小的误码率,较大的码字容量和较大的频谱效率,是OCDMA(光码分多址)系统地址码较好的选择。
The generation of address codes based on Gold sequence is studied. The correlation and spectrum efficiency are analyzed and compared with the performance of Orthogonal Orthogonal Codes and Prime Digital Codes. The analysis shows that the Gold sequence is a code word with better autocorrelation and cross-correlation performance, a larger code word size, a smaller bit error rate under the same parameters, a larger code word size Large spectral efficiency, OCDMA (optical code division multiple access) system address code better choice.
