关于CDT CRC校验的问题

sdwhlcf

我看规约里有个CRC校验表，那个表是如何得到的，我查了相关资料，有的人代码把那种校验码叫正码，谁能指点下，搞不定了？现在行业常用的都是反码，这个反码表我能计算出来！
; W$ ?) M, F" d) E; D0 ?
0 f3 ^; t$ i: G( `9 h本规约采用CRC校验，控制字和信息字都是（n、k）=(48,40)  码组，生成多项式为
# K* ~( i; w' r3 K- |. M1 uG(X)=X8+X2+X+1,陪集码为FFH。按4.2条所述发码规则的顺序以 G(X)模2除前5个字节，生成余
式R(X)。以R(X)作为校验码。若用查表法，信息字、控制字基本码元的中间余式见
