Hi, I would like to know if it is normal to include a 2nd redundant echo canceler algorithm for line echo cancellation. I came across brief notes on the internet that suggested use of two echo cancelers in line echo cancellation. The additional echo canceler is enabled in case the primary echo canceler goes out of bounds (diverges). I could not find much useful information on this subject. ...

Hi Dhar and to other group members, the form of the exponential filter is not shown in your post. can you pleas= e re-post it again? and by the way, what should be the gain factor of the rectangular sliding w= indow? I doubt that it is 1. and lastly, what measurement method must the detector do? is it the RMS met= hod specified in the recommendation? thanks to you all and have a goo...

Hello, I was wondering if anyone has any idea about MC-echo cancellation using BSS, and if there are any available demos or algorithms. I found the ECoBliSS file of Schobben and Sommen, but i was wondering if there are any other examples. Also, does anyone know if it is available as a product in the market? Thanks

I am implementing a LMS adptive filter denoising system. And I got a noisy signal A, and also a noise signal B. The B is corrected with noise of noisy signal A. y(n) = conj(W)* U(n); e(n) = d(n) - y(n); W(n+1) = W(n)+mu*U(n)*conj(e(n)) ? 1. Which signal should act as main input signal U,and which should act as the desired signal D? noisy or noise? why? can I exchange their roles? Ple

hello everyone.. im stephanie a graduating student..and im doing a thesis about echo cancellation in communication by a neural network using the LMS algorithm...i just want to ask help from you guys about how to delay a voice signal???how to delay this signal.. s=(1+0.2*sin(2*pi*fa*t)).*sin(2*pi*f*(1+0.02*cos(2*pi*fm*t)).*t); and then may i ask also an examp...

Hi All, I'm doin a project on NETWORK ECHO CANCELLATION and need help to choose the best ADAPTIVE ALGORITHM. Everywhere its said, RLS is the best adaptive algo as well the most complex and unstable.With the now available workholic DSP/FPGA can't we bet on RLS for the increased perfomance? or is still there an unknown force which prevents us from doin so?

Hi! I am new to the subject. Could anyone tell me how to simulate an echo canceller? I mean, if I want to develop a new device, what software tools can I use to model it before it is implemented in hardware, say, on the DSP. Is it possible to use Matlab or other software for that purpose? Stanislav
