Abstract
The specification discloses systems and methods that provide improved capability to detect and decode encoded telemetry data. More particularly, the specification discloses embodiments for detecting and decoding telemetry data by receiving a plurality of waveforms comprising encoded telemetry data. A first set of outputs is detected from the encoded telemetry data using a first set of filtering and detection parameters, and a second set of outputs is detected substantially concurrently from the encoded telemetry data using a second set of filtering and detection parameters. The sets of outputs are merged to produce decoded telemetry data.

A method comprising:
- receiving a plurality of waveforms comprising encoded telemetry data;
- detecting a first set of outputs from the encoded telemetry data using a first set of filtering and detection parameters;
- detecting a second set of outputs from the encoded telemetry data using a second set of filtering and detection parameters, the detecting the second set of outputs substantially concurrent with detecting the first set of outputs;
- and
- merging the first set of outputs and the second set of outputs to produce decoded telemetry data.
A telemetry system comprising:
- a bottomhole assembly operable to transmit encoded telemetry data to the surface;
- at least one sensing device operable to detect the encoded telemetry data;
- and
- a surface system coupled to the at least one sensing device, the surface system operable to acquire the encoded telemetry detected by the at least one sensing device,
- wherein the surface system
- detects a first set of outputs from the encoded telemetry data using a first set of filtering and detection parameters,
- detects a second set of outputs from the encoded telemetry data using a second set of filtering and detection parameters, the detecting the second set of outputs substantially concurrent with detecting the first set of outputs, and
- merges the first set of outputs and the second set of outputs to produce decoded telemetry data.
Software instructions on one or more information carrier media, wherein the instructions, when executed in a telemetry system, cause the telemetry system to:
- receive a plurality of waveforms comprising encoded telemetry data;
- detect a first set of outputs from the encoded telemetry data using a first set of filtering and detection parameters;
- detect a second set of outputs from the encoded telemetry data using a second set of filtering and detection parameters, the detecting the second set of outputs substantially concurrent with detecting the first set of outputs;
- and
- merge the first set of outputs and the second set of outputs to produce decoded telemetry data.
