This transmitter model is part of a simple hypothetical layered radio. It produces detailed transmissions that have separate representation for all simulated domains. The levelOfDetail parameter controls which domains are actually simulated, but all parameters relevant to the error model are always set on the transmission.

With the highest level of detail, the produced transmission contains the following:

• a separate packet to represent the PHY frame
• precise bit representation of the whole packet
• precise bit representation after scrambling, fec encoding, and interleaving
• precise symbol representation of the whole packet including physical header
• narrowband analog representation using scalar transmission power

NOTE: the current implementation doesn't support pulse shaping and digital analog conversion.

This transmitter model supports scrambling, convolutional coding, interleaving, and modulating various amplitude and phase-shift modulations. The main purpose of this model is to provide a basic infrastructure for further development and experimentation.
