Re: LMS algorithm for noise cancellation in speech

hi all,
i am trying to implement the LMS algorithm that cancells the background
noise from the input signal needed.i have tried it for sin wave it is
working fine.But when i have tried to give noise mixed input signal(wav
file) it was not working properly..

the scenario i followed is
first i took a wav file as the input signal and then created the noise
input with rand() fn/. in matlab.Then i mixed both and took it as the
primary signal.The delayed input signal was taken as the reference
signal.
.

i am new to ANC .. can anyone help me in proceeding this work?

thanks and regards,
Radha

How to you expect to adapt to a random signal? Do you believe it is possible for DSP to use premonitions about what the noise will do next? :-)
