| 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. |
