Using the Communications Blockset with MATLAB (Getting Started)

Getting Started

Viewing the Signal and Error Data in the Workspace

After running a simulation, you can display individual frames of data. For example, to display the tenth frame of Tx, at the MATLAB prompt type

```
Tx(:,:,10)
```

This returns a column vector of length 4, corresponding to the length of a message word. Usually, you should not type Tx by itself, as this displays the entire transmitted signal, which is very large.

To display the corresponding frame of errors, type

```
errors(:,:,10)
```

This returns a column vector of length 7, corresponding to the length of a code word.

To display frames one through five of the transmitted signal, type

```
Tx(:,:,1:5)
```
