本文讨论了我国电力系统远动通信中的编码问题,分析了如何选择缩短BCH码最优生成多项式和最佳同步多项式问题。文中提出了比较适合于我国电力系统远动通信的(32,24),(40,32),(48,40)码的最优生成多项式g(x)=x~8+x~5+x~3+x~2+x+1以及它们的最佳同步多项式P(X)={x~n}或{x~(126)}。文章不仅对这个结论从理论上进行了分析,而且通过大量的计算进行了有力的验证,同时与IEC的TC-57委员会提出的编码方案作了比较。
This paper discusses the coding problems in China’s power system telecontrol and analyzes how to choose the shortest optimal BOP polynomial generation polynomial and the optimal synchronization polynomial problem. In this paper, the optimal generator polynomials (x) = x ~ 8 + x ~ 5 + x (32,24), (40,32) and (48,40) are more suitable for the long- ~ 3 + x ~ 2 + x + 1 and their optimal synchronization polynomial P (X) = {x ~ n} or {x ~ (126)}. The article not only theoretically analyzes this conclusion, but also validates it through a large number of computations. At the same time, it compares with the encoding scheme proposed by IEC-TC-57 Committee.
