摘要
在简单地讨论了循环码基本特性的基础上,导出了一个利用程序计算循环系统码的校验位的流程。按照导出的流程用QBASIC语言编制了一个通用的CRC校验码编码的计算程序。利用给出的程序,可方便地计算出任意给定的码生成多项式及信息码元下对应的系统码的CRC校验位。
In this paper, by giving briefly discussion on the properties of the cyclic code, a procedure of caculating the cyclic system code's check bits is deduced. Following the prochrlure. a program with QBASIC is made out. With the give program, one can caculate the system code's CRC check bits for any given system code generator polynomial g(x) and message code bits at ease.
