摘要：
Through-the-earth (TTE) communication is of great significance to establish the information transmission with the trapped people at the first time and ensure the smooth flow of information. The complex electromagnetic environment of the terrestrial channel brings many difficulties in wireless signal transmission. This paper proposes an orthogonal frequency division multiplexing (OFDM) signal design scheme of electrode-based TTE communication. The scheme, which has intense penetration and high reliability, designs the frequency and modulation mode of the subcarrier according to the electromagnetic characteristics of earth channel and noise interference. This paper also provides the results of field experiments to show the performance of this OFDM signal.
