| 摘 要： | 在最佳PCM群同步码的研究工作中,我们继文1],2]所发表的第一批新成果(N=31～42位最佳码)之后,又搜索出了第二批新成果——N=43～54位最佳码,并于1990年4月6日完成了编辑整理;对其中每种字长,还搜索出了前8个好码,并在码元误概率为P_0=0.1及容错数E=0～5时,计算出了各自的误同步概率;此外还发现了若干岐码。

| Abstract: | In this paper, twelve optimum PCM group synchronization codes (N = 43 to 54) are presented. These optimum codes are the second new results of our research and the newest development of the category of optimum codes up to now in the world.The patterns,the error synchronization probabilities (when E=0 to 5, P = 0.1) and the important characteristic data for these optimum codes are published in two tables (Table 1 and Table 2).In addition,the key theories for advanced searching methods are also presented in this paper. |
