数字轨道电路MSK信号的一种纠错解调方法
An Error Correcting Method for Decoding MSK Signal in Digital Track Circuit
【摘要】 主要根据当前我国铁路发展的实际需要 ,针对国外数字轨道电路系统的基本原理 ,提出了MSK信号的一种新型的解码方案 .该方案实现起来简单、快速 ,在信号非冗余情况下 ,对译码结果能够实现一位自纠错功能 ,可以大大提高译码的正确率 .
【Abstract】 According to the practical requirement of the development in China railway, a new scheme for decoding MSK signal is proposed in this paper, on the basis of the basic principle of digital track circuit from abroad. The characteristic of this scheme is easy and quick for implementation. Under the condition of non redundant signal, one bit self error correcting can be realized by this scheme. Thus it greatly enhances the correct rate for decoding.
