Omap3530 Tps65950 noise cancelation

A dialog at the Tps659xx PMU forum:

Hi, 

referring to pag 682 of swcu050e.pdf (Technical Reference Manual ver E):

 

NOTE: The main microphone captures the voice and surrounding noise, whereas the

submicrophone captures only the surrounding noise. The noise cancellation is performed by

the external host processor by subtracting the submicrophone data from the main

microphone data, thus keeping only the voice data.

Does someone have implemented this solution?
Could you plz suggest me an implementation from software and hardware point of view?
Many thanks.
Andrea

Hi Andrea,

This has to be done on OMAP side in DSP algorithms. I dont know if anyone has implemented this. You can ask on OMAP forums and may get some leads.

 

Regards,

Gandhar.

Documant also say: Secondary microphone for noise cancelation.

I'm also wondering, if it is implemented as software which method used? for exp:LMS

How can we reach this algorithm? Is there any documant?

Thanks
