Getting Started

Connecting the Blocks

Next, connect the blocks as shown in the following figure. Make sure to connect the arrow from the Binary Symmetric Channel block to the input port labeled Rx on the Error Rate Calculation block. To learn how to do this, see Connecting Blocks.

The next section explains how to draw the upper branch line in the model.

Drawing a Branch Line

The upper line leading from the Bernoulli Binary Generator block to the Error Rate Calculation block, shown in the following figure, is called a branch line. Branch lines carry the same signal to more than one block.

To draw the branch line, follow these steps:

1. Right-click the line between the Bernoulli Random Generator block and the Binary Symmetric Channel block.
2. Move the mouse pointer to the input port labeled Tx on the Error Rate Calculation block, while pressing the right mouse button.
3. Release the mouse button. The end of the branch line should connect to the input port of the Error Rate Calculation block.
4. Click the horizontal section of the branch line and drag it upward until the line is above the Binary Symmetric Channel block.

The model should now appear as in the following figure.
