【 摘 要 】

Work is being done to transmit data via our through-the-earth communications system. After evaluating several methods, quadrature phase shift keying was selected as the preferred method. Coding was added to voice communication to increase reliability when two-way radios are being used as input and output devices. For in-mine communication, we are studying to increase the versatility of our system through the addition of Ethernet ports.
