Communications Toolbox

Simulating a Communication System

The examples so far have performed tasks associated with various components of a communication system. In some cases, you might need to create a more sophisticated simulation that uses one or more of these techniques:

• Looping over a set of values of a specific parameter, such as E_b/N₀, the alphabet size, or the oversampling rate, so you can see the parameter's effect on the system

• Processing data in multiple smaller sets rather than in one large set, to reduce the memory requirement

• Dynamically determining how much data to process to get reliable results, instead of trying to guess at the beginning

This section discusses these issues and provides examples of constructs that you can use in your simulations of communication systems. The topics are as follows:

• Using BERTool to Run Simulations

• Varying Parameters and Managing a Set of Simulations
