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

With the highest level of detail, the reception contains the following:

• a separate packet to represent the PHY frame
• precise bit representation of the whole packet
• precise bit representation before descrambling, fec decoding, and deinterleaving
• precise symbol representation of the whole packet including the physical header
• narrowband analog representation using scalar transmission power

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

This receiver model supports descrambling, convolutional decoding, deinterleaving, and demodulating various amplitude and phase-shift modulations. The main purpose of this model is to provide a basic infrastructure for further development and experimentation.
