摘要： In a code transmission scheme for a communication system using error correcting codes, the transmitting side generates at least one transmitting side syndrome value by carrying out a syndrome calculation for the information to be transmitted, and transmits to a receiving side at least one information packet containing the information to be transmitted and at least one redundant packet containing the transmitting side syndrome value. Then, upon receiving at least a part of the information packet and the redundant packet, the receiving side obtains at least one receiving side syndrome value by carrying out a syndrome calculation for an information contained in the information packet as received, and performs error correction, if required, by calculating a difference between the transmitting side syndrome value contained in the received redundant packet and the receiving side syndrome value, so that a circuit size and an amount of software programs can be reduced without affecting the error correction performance.
摘要翻译：在使用错误校正码的通信系统的码传输方式中，发送方通过对要发送的信息进行校正子计算来生成至少一个发送侧校正子值，并向接收侧发送至少一个包含要发送的信息和包含发送侧综合征值的至少一个冗余分组。然后，在接收到信息分组和冗余分组的至少一部分时，接收侧通过对包含在接收到的信息分组中的信息进行校正子计算来获得至少一个接收侧综合征值，并进行纠错，如果需要，通过计算包含在所接收的冗余分组中的发送侧校正子值与接收侧校正子值之间的差异，使得可以减小电路大小和软件程序的量而不影响纠错性能。
