Initital Convergence Reason - sonicbio - Apr 29 16:40:00 2002

Hello All, I have been working on building up a acoustic echo canceller on a digital phone based on PCM. With many reference I have found with this group on double-talk functionality and near-end noise cancellation, I have discovered that a more robust system will be inverse-propertionate to the rate of initial convergence. Where does this result from? With faster and faster DSPs on the market, I would assume a simple adaptation process would not affect that much to the processing speed. Yet, the phone still seems to have a slower initial convergence. Tom |
