Echo Canceller for SigmaDSP

Hi TomY,

There is a normalized least mean squares (NLMS) filter available in SigmaStudio, which is the basic building block for echo cancellation systems, but it is not yet documented with examples. We have a plan to eventually make an example project, or perhaps a reference design, based on this concept. However, the timeline for the project has not been set, and the project is on hold. In theory, the tools are available in SigmaStudio, but I do not yet have the understanding or expertise to use them properly.

Hi, BrettG

Thank you for your answer.

I understood the current situation.

I hope the detailed description of NLMS will be available in the document as soon as possible.

Merry Christmas and Happy New Year

Hi BrettG,

Good day.

May I know the document/reference design for echo cancellation application with SigmaDSP is ready?

Could you please kindly point me where could I get it?

Thanks.

Regards,

Tin Tin

Hi Tin Tin,

Brett is no longer with Analog Devices. I will respond to your question on echo cancellation documentation in the other thread: ADI Sigma DSP for echo cancellation
