Does anybody have an implentation of the RLS algorithm for adaptive filters?? Please??

[Ken Kearney]

Hi,

I'm trying to design an adaptive filter using the RLS algorithm. I don't want to spend ages doing one if there's one already available. Any help would be fantastic

I have not been able to find any on NI's website. They don't have any example programs for this or KnowledgeBases discussing it. Hopefully someone else out there has one for you!

thankyou!

Can you see this link?  This topic is way outside my "experience base", and I don't have these toolkits installed, but hope this helps.

And here is a post that begins "I have successfully implemented the RLS Algorithm in LabVIEW".  Don't know if he's talking about Adaptive Filters, though ...

what do you mean?

[trusted47]

if you look closely i posted this question aswell, that you have refferred to. it is true that i have implemented the algo.

the only thinng is that i am having trouble with the input. as you can see in the link!

Maybe you could re-phrase your question. Is the problem when you add noise to the output or something to do with the input? What exactly?

[trusted47]

the question is simple. is just want to know how to generate  d(n) i-e desired signal for RLS algorithm. the desired signal is the input to the system which is siganl plus channel noise (we say it is Gaussian), so signal + gaussian . the Problem that i face is that the tap weights never change no matter what i do to the input signal. they only change when i change the low cut off the FIR filter.
