Discrete multitone based wireline telemetry system for single-mode telemetry applications

A surface acquisition module for a discrete multitone modulation (DMT) system, the surface acquisition module comprising:

• one or more memories collectively storing instructions;
• and
• one or more processors communicatively coupled to the one or more memories, the one or more processors being collectively configured to execute the instructions to cause the surface acquisition module to:
• initiate a first training sequence with a downhole telemetry module at a first bandwidth of a plurality of bandwidths via a communication link between the surface acquisition module and the downhole telemetry module;
• receive, during the first training sequence, a set of training tones from the downhole telemetry module via the communication link;
• measure a respective power of a first training tone of the set of training tones and a second training tone of the set of training tones;
• automatically select a second bandwidth of the plurality of bandwidths 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 being greater than the first bandwidth, and the second bandwidth being automatically selected when the power of the first training tone and the power of the second training tone satisfy a predetermined condition;
• and
• exchange data with the downhole telemetry module during the communication session according to the second bandwidth.
