| description | According to characteristics of various modulation and demodulation modes, bit error rate of modulation modes including binary amplitude shift keying, binary frequency shift keying and binary differential phase shift keying under different demodulation modes were simulated and compared on the basis of characteristics of mine through-the-earth communication channel. The results show that the binary frequency shift keying coherent demodulation mode can reduce the bit error rate in transmission process of voice signal effectively, and improve reliability and accuracy of the through-the-earth communication with certain ability to resist noise and frequency selective fading, which is more suitable for modulation and demodulation of voice signal in mine through-the-earth communication. |
