Computing Theoretical BERs

You can use BERTool to generate and analyze theoretical BER data. Theoretical data is useful for comparison with your simulation results. However, closed-form BER expressions exist only for certain kinds of communication systems.

To access the capabilities of BERTool related to theoretical BER data, use this procedure:

  1. Open BERTool and go to the Theoretical panel.

  2. Set parameters to reflect the system whose performance you want to analyze. Some parameters are visible and active only when other parameters have specific values. See Available Sets of Theoretical BER Data for details.

  3. Click Plot.

For an example that shows how to generate and analyze theoretical BER data via BERTool, see Example: Using the Theoretical Panel in BERTool.

Also, Available Sets of Theoretical BER Data indicates which combinations of parameters are available on the Theoretical panel, as well as which underlying functions perform computations.
