A system is disclosed that may include an Automatic Gain Control (AGC) module configured to automatically adjust the gain of a receiver, which is configured to receive a signal. The signal includes a number of commands, which have a characteristic command length and a characteristic command interval. The command length may have a substantially shorter duration than the command interval. The system may also include a slicer configured to interface to a command processor. The system includes a command processor communicatively coupled with the AGC module and/or the slicer for providing a notification to the AGC module and/or the slicer associated with the ends of the commands. The AGC module is configured to adjust the gain of the receiver and the slicer threshold voltage is updated when the notification is received from the command processor.
