Turbocode ?

[ben500fr]

Does somebody knows how to create a turbocode corect error code?

Thank's

What is a "turbocode corect error code"?

[ben500fr]

Corrector errore code can be viterbi, reed-salomon, hamming......

In french: "code correcteur d'erreur" 😉

I seek someone knows a turbocode vi.

Baybe there is a toolkilt to do this in LabVIEW 8.5 (I'm on 7.1 but I can pass on 8.5) ?

[altenbach]

quote from: http://en.wikipedia.org/wiki/Turbo_code

"The Complexity of these algorithms and the fact that these algorithms have encumbering software patents are a detractor of implementing these algorithms in a system"

Sorry, I haven't heard of any LabVIEW implementation.

[ben500fr]

So I will have to code it olone?

[smercurio_fc]

The Wiki page that altenbach provided has at the bottom "External Links". One of these points to an open-source library that can be used in Matlab. I would suggest starting there if you don't get any responses on this board.

Hi ben500fr,

I am sorry but National Instruments doesn't provide such code. You will have to do it by yourself or find it on the web.

Yes, you are on your own. But you will learn SO MUCH MORE that way. If you have MATLAB and the LV Professional Development system you can use a Turbo Code program written in MATLAB and plug it into LV with the MathScript node. There are Turbo Code examples written in MATLAB on the internet.

But I don't have a licence for mathlab

A turbo code isn't very complicated to do, the only thing is to have a soft viterbi.

In LV the coder vterbi is "hard": you give to it a stream of 0 or 1 and it give you a new stream of 0 and 1.

In a soft coder; you give him a stream of number into -127 and 127

-127 is a zero

127 is a one

Question: does somebody has a soft viterbi (or reed-solomon) coder?????

Thank's
