Abstract Realistic simulation is an essential step in the development and testing of communications systems. Toward that end, it is essential to create an accurate model of the operating environment as well as the system components. This report details the derivation and creation of three such models developed for use with Simulink, the graphical user interface for Matlab (The Math Works, Inc.). The models simulated are (1) an Unshielded Twisted Pair (UTP) Cable Communications Channel, (2)...
