Downhole telemetry system using discrete multi-tone modulation in a wireless communication medium

摘要

A communication system usable in a borehole in which a downhole modem wirelessly communicates with a surface modem using discrete multi-tone ("DMT") modulation. The communication may be one-way (i.e., from downhole modem to surface modem, or vice versa) or two-way between the two modems.
