Communications Blockset

Exploring the Model

Once the model is open, you can explore it in several ways. You can begin to explore even before you run the simulation:

• "Read" the block diagram starting with the Bernoulli Random Binary Generator block in the upper left corner, following the arrows, and ending with the Display block in the center.

Note that the block marked "Info" does not function during the simulation but rather links to the HTML version of this documentation.

• Double-click on any block to see its parameter dialog box. This dialog box briefly describes the block, shows its parameter values if the block has parameters, allows you to change any of the parameter values, and also includes a Help button that links to the detailed HTML reference page for the block.
• To see the blockset library in which any Communications Blockset block resides, right-click on the block, select Link options, and then select Go to library block. This shows you where to find the block if you later want to use it in your own model. The Link options function is inactive for built-in Simulink blocks, such as the Display block.

Running the Simulation

Run the simulation by selecting Start from the model window's Simulation menu. While the simulation runs, the bottom bar of the model window displays the time, T, and the Display block in the center of the block diagram displays three numbers that represent the simulation's error rate information (explained below). Once it starts, the simulation runs until you select Stop from the model window's Simulation menu.
