You should use awgn function from communications package.

Max,
Thanx for your replies...you mean the Matlab communication tool box? it is similar to octave syntax?

I mean Octave communications package. Before You use it, You should load this package by typing: "pkg load communications" (providing that You installed it earlier).

Are You sure that this package isn't installed? You can check it by typing "pkg list" in Octave command line. This command shows all packages which are already installed. Maybe it would be enough to load it?

If You use Windows You usually don't have to install communications package because it's installed by default. You have to load it only. You can do it typing "pkg load communications" in an Octave command line.

However if You use Linux you have to install package by running Octave, and typing "pkg install communications-X.Y.tar.gz" (I don't know which version You have). Obviously at the end You should load the package as I described above.

More information about installing and removing packages You find there: Packages - GNU Octave

Could You tell me which OS do You use?

Well, I think You should install Octave ver. 3.2.4 for Windows, then run it, and type: pkg load communications. There is no need to install communications package separately because it's installed by default. That's all.

Octave for Windows You can find here: Octave-Forge
