摘要: |
信息在无线信道中传输不可避免地会出现误码,本文即提出一种实用的无线信道纠错方案,包括循环冗余校验(CRC)编码、Golay(24,12)编码以及交织,其算法简单,易于实现,成本低廉,并可抗较高的信道误码,且全部可用软件实现。在理论分析的基础上,文中最后给出了实验测试结果,并指出其适用于实际通信系统。 |

An Applied Scheme for Error Correction over Wireless Channel |
|
() |
Abstract: |
Errors are unavoidable when the signal is transmitted over channel, especially over the wireless one. This paper puts forward an applied kind of error correction scheme including CRC, Golay(24,12) coding and interleaving. The simple algorithm proposed has a low complexity implementation and cost but better performance on error correction which can be achieved by software. On the basis of theoretical analysis, this paper presents experimental test results and indicates that the scheme is suitable for application in practical communication systems. |
