I would like to implement a module which keeps a constant carrier running and transfers packets of data at different times. In other words, using ASK (or OOK) modulation, I would like to always be transmitting ones (carrier is at full amplitude) except for certain periods where I will "pause" the carrier (carrier amplitude is zero or some smaller amplitude).
How can I do this without supplying an "infinite" number of ones (with zeros inter-weaved where I want them) in my packets? I would like to be able to have a constant "full carrier amplitude" until I call some method like "send_packet(data)."
Any thoughts/suggestions/examples? Corrections in my thinking?
