Getting Started

Running the Channel Noise Model

To run the model, select Start from the Simulation menu. After a few seconds, the model will stop automatically.

To see all three boxes in the Display block, you must enlarge the block slightly, as follows:

1. Select the Display block and move the mouse pointer to one of the lower corners of the block, so that a diagonal arrow appears on the corner, as shown.

   

2. Drag the corner of the block down with the mouse until three windows appear, as shown.

   

The Display block displays the following information:

• The bit error rate
• The number of errors
• The total number of bits that are transmitted

Note that the exact values that appear will vary, depending on the Initial seed parameters in the Bernoulli Binary Generator block and the Binary Symmetric Channel block.

Since the Target number of errors in the mask for the Error Rate Calculation block is set to 100, the simulation stops when 100 errors have been detected.

To save the model, select Save from the File menu, type a name for the model, such as channelnoise, in the File name field, and click Save.
