Abstract
The present disclosure provides techniques and apparatus for discrete multitone (DMT) modulation communications for single-mode telemetry. An example technique involves a surface acquisition module initiating a first training sequence with a downhole telemetry module using a first bandwidth of a plurality of bandwidths via a communication link between the surface acquisition module and the downhole telemetry module. A second bandwidth of the plurality of bandwidths is automatically selected for a communication session between the surface acquisition module and the downhole telemetry module using the communication link, based on the first training sequence. The second bandwidth is greater than the first bandwidth. Data is exchanged with the downhole telemetry module during the communication session based on the second bandwidth.
