Abstract
A method may include communicating a command into a wellbore from the surface. The method may include determining a command to be sent to a downhole tool, and translating the command into a message, the message including a sequence of codes. The method may include rotating the drill string substantially at the set point RPM for a predetermined duration and measuring the rotation rate of the drill string. The method may include identifying the received set point RPM and rotating the drill string consistent with a first code value of a first code of the message as encoded. The method may also include decoding the first code and rotating the drill string consistent with a second code value of a second code of the message as encoded. The method may also include decoding the second code, identifying the command from at least one of the decoded first and second code and executing the command.
