Performance Evaluation

Simulating a communication system often involves analyzing its response to the noise inherent in real-world components, studying its behavior using graphical means, and determining whether the resulting performance meets standards of acceptability. The sections in this chapter are as follows.

Because error analysis is often a component of communication system simulation, other portions of this guide provide additional examples.
