| Abstract: | Railway FSK signal is a kind of low-frequency modulated carrier frequency signals. In order to achieve accurate demodulation of the FSK signals sent by ZPW-2000 series code-transmitting device, a new railway FSK signal detection system based on Floating-point DSP technology is designed. Tests have been macle to the system and the results show that it can detect various data rapidly and accurately after the dcmodulation of FSK signals. |
