Signal generator models are fundamental to the simulation of communications systems. The whole point of simulation is to assess how various types of processing (either intentional or unintentional) will impact the characteristics of signals and their ability to convey information. The utility of simulation as an analysis tool depends upon the ability to create signal models that adequately capture the salient features of signals from the real world.

3.1 Elementary Signal Generators

The unit impulse and unit step functions are two mathematical signal models that are often used in the analysis and characterization of the constituent parts of a wireless communication system. The impulse response of a linear system is ...
