* \ingroup spectrum

* This struct provides the generic signal representation to be used by
* all wireless technologies. Any specific wireless technology is
* allowed to define additional signal parameters by inheriting from this
* struct and providing additional member variables. This makes sure
* that a minimum set of parameters (in particular, the ones needed
* for interference calculation) is
* common across all wireless technologies, while at the same time
* allowing each technology to have its own specific signal parameters.
*
* Furthermore, since the signal parameters specific of every technology inherit
* directly from this struct, each PHY can test (by using a dynamic
* cast) if a signal being received belongs to a given technology or not.
*
* \note when inheriting from this class, make sure that the assignment operator and the copy constructor work properly, making deep copies if needed.
