Layer1. A SIMULA Context for Simulating the Operation of Communication Systems

摘要

Layer1 is a SIMULA class that provides a set of object templates useful in developing simulations of communication system operation. Layer1 is oriented toward the modeling of high frequency (HF), frequency-hopped, radio communication systems; but it is sufficiently versatile to support the simulation of both radio and hardwired communication systems thaat use other portions of the frequency spectrum. In this document we described the layer1 methodology and give an example of its application to simulating an HF radio communication system that uses a carrier-sense multiple-access (CSMA) protocol. The purpose is to introduce the reader to the object-oriented approach used to develop the layer1 code and to give him or her enough information to construct a simulation in a layer1 context. Keywords include: Communication systems, Simulation, SIMULA, Object-oriented, and Carrier-sense multiple-access.
