Hi all,

I'm a newbie so bear with me. I'm trying to carry out noise 
cancellation on speech using the LMS algorithm but i'm having no luck 
at doing so. It was successful when a sine wave was my reference signal 
source but i'm now using white noise as my reference signal. Can anyone 
suggest a suitable values for the filter order and convergence rate? I 
Someone said just using an FIR filter and the LMS would not be adequate 
to cancel white noise. 

I would also like to implement it in real-time. What are the 
constraints? 
Any sort of help will be greatly appreciated.
