Study and Application of Error Correction Technology in Embedded Systems
Author(s): 
Pages: 95-98
Year: Issue:  z1
Journal: JOURNAL OF CHENGDU UNIVERSITY OF INFORMATION TECHNOLOGY

Keyword:  嵌入式检纠错技术RS码CRC;
Abstract: 研究了目前数据传输、数据存储领域中广泛使用的CRC(循环冗余校验)以及RS码(Reed-Solomon码),在16位单片机环境中软件实现两种算法.并模拟出实际通信中信道的突发错误和随机错误,通过实验统计数据的方式比较两种检纠错算法,分析其在不同信道质量下的检纠错能力和对系统资源的消耗状况.系统通过简单的改造和移植就能成为其他嵌入式系统中的数据校验传输模块;同时为在构建特定信道环境下的嵌入式数据通讯系统时,选择合适的检纠错技术提供了理论和实验依据.
