Receiver automatic gain control (AGC) and slicer

A method comprising:

• receiving a signal from a transmitter at a receiver, the signal comprising a plurality of commands having a characteristic command length and a characteristic command interval, the command length having a substantially shorter duration than the command interval;
• determining the end of at least one of the plurality of commands;
• providing a notification associated with the end of the at least one of the plurality of commands;
• automatically adjusting the gain of the receiver only when the notification is received;
• and
• generating a slicer threshold voltage, wherein a threshold for the slicer is adjusted only when the notification is received.

A system comprising:

• an Automatic Gain Control (AGC) module configured to automatically adjust the gain of a receiver, the receiver configured to receive a signal from a transmitter, the signal comprising a plurality of commands having a characteristic command length and a characteristic command interval, the command length having a substantially shorter duration than the command interval;
• a slicer configured to convert an analog output of the receiver to a digital output;
• and
• a command processor communicatively coupled with the AGC module and the slicer for providing a notification associated with the ends of the plurality of commands, the AGC module configured to adjust the gain of the receiver and the slicer configured to adjust a threshold only when the notification is received from the command processor.
