Most basic ones use something like PPM to modulate servo positions like in pic related. You need a RF oscillator, usually at 27MHz which you modulate with PPM and then decode at receiver. This is the old school way of doing this. Newer 2.4GHz modules use more advanced modulation schemes. You can also just use any of the shelf RF modules for le arduino and send digital packets to the receiver.
