摘要
在多值数字传输系统中要求数据传输速率要高,差错概率要低,即确保数据传输的有效性和可靠性.为了判断多值数据在传输过程中是否出错,需要在接收端进行校验.一般二进制校验方法不适用校验多值数据,给出的重复码和互补码,可适用于任意值数据校验.
In order to ensure the reliability and the effectiveness of data transmission in the multiple value digital transmission system the data transmission speed should be high, and the mistake should be avoided. To judge whether multiple value data in transmission make mistakes or not, check is needed on the receivingend. Normally,the check method of binary is not suitable to the multiple value data. The duplication code and complementary code given in the paper can be applied to check arbitrary value data.
