 |======================================| 
    Data Communications Toolbox  v6.00
 |======================================| 
 [for Scilab-5.0 (and laters)]

This toolbox brings you some codification/decodification 
algorithms used in data transmition at link level.

With this version you can encode and decode in: 

- NRZL, NRZI
- AMI
- Manchester & Diferential Manchester
- B8ZS
- HDB3
- BPSK
- 8QAM
- QPSK
- 8PSK

It's intended for educational purposes, to understand different encoding
schemes, their properties, spectrum and noise inmunity and make comparisons
among them.

Installation
============

To compile this toolbox, Scilab 5.0 must have been installed with the
 'Development Tools' module. This is the default case in Linux. In Windows,
you must select 'Custom setup' during instalation, and then check the 
'Development Tools' module.

Close Scilab. Unpack the toolbox and save the content under the 'contrib' 
directory. This folder is inside share/scilab/ from the scilab root directory
(e.g. '/home/myuser/scilab-5.1/share/scilab/contrib') for UNIX, and in the
scilab root directory (e.g. 'c:\Program Files\scilab-5.1\contrib') for 
Windows).

After re-starting Scilab, click on the 'Editor' option from the 'Applications'
menu, and open the file 'contrib/Data_Communications/builder.sce' .
Then, click on  'Execute' (menu at top) and select 'Load into Scilab'.
Wait a couple of seconds until "Done building!" appears on the command line.
Do not click anywhere until seeing this! At this time you have succesfuly
istalled the toolbox.

Each time you will use any function from the toolbox, you will need to
load it into Scilab workspace. For that, open the 'Toolboxes' menu and
select the option 'Data_Communications'. This operation should be repeated each
time you restart Scilab.

Enjoy it!
