Abstract
A computer software program simulates a communication network using network characteristic information provided by communication network designers. When a network designer selects a particular location within the network, the software consults the network characteristic information to predict a signal attribute of a simulated signal received at the selected location. The predicted attribute is used to modify a template signal to produce a simulated output signal, and the simulated output signal is presented for consideration by the network designers.
