System simulation

Abstract

The concept of system simulation is an exceptionally broad topic. The term itself, system, does not have a rigid definition and in practice the term is applied to represent dramatically differing levels of circuit integration, complexity, and interaction. In a simple sense, the term is applied to represent the interconnection and interaction of several electrical circuits. In a broader sense, such as in communication systems, the term may be applied to represent a much higher level of complexity including part of, or the composite mobile radio, base unit, and the transmission medium (channel). Regardless of complexity of the level, the issue of simulation is of critical importance in the area of design and optimization.
