| 摘 要： | 指出了ＥＳＡ、ＣＣＳＤＳ标准所推荐的４２个１６位字长的航天遥控系统地址同步码，其误同步概率太大，有值得改进的必要，介绍了作者研究得出的一组６４个１６位字长的准最佳地址同步码，并且用表格详细地就两者的汉距离和误同步概率作了对比，表明其研究成果远优于上述两种国际标准中的地址同步码，此外，考虑到发展的需要，还研究出一组２４位准最佳地址同步码（共６４个），供有关读者参考。

| Abstract: | In this paper,we considered and investigated a set of 42 address synchronization codes (with word length N= 16 Bits) for space remote-control systems. These codes were recommented by (CCSDS Standards) and (Satellite Remote-Control Standards,ESA). The erroneous synchronization probabilities of above-mentioned codes are regretfully too greate. For this reason,we presented a new set of 64 quasi-optimum address sychronization codes with word length N= 16 Bits also. It is a new result based on our research for searching optimum PCM group synchronization codes. Both characteristics have been contrasted. In reality,our codes are better than foreign codes. In order to meet the future requirement,we have searched out a set of 64 quasi-optimum address synchronization codes with word length N=24 Bits in addition. |
