摘要
This article describes the application of extremely low-frequency minimum shift keying (MSK) signals to ground electrode current field through-the-earth (TTE) communications. Firstly, the applicable MSK signal operating frequency is analyzed by constructing a ground electrode current field TTE communications channel model. Secondly, the MSK signal is designed to be suitable for the channel environment. Finally, the TTE communications tests are performed at 200 and 500 meters to analyze the received MSK signals for synchronization and communication performance. The results show that the extremely low-frequency MSK signal has strong penetration and anti-interference and can achieve signal synchronization and information transmission at 200 and 500 meters.
