Packet loss concealment(PLC) for G.726

Started by balyans.rm January 23, 2006
Hi All,
Does anyone has any information ( performance, implementation,
productsetc.) about ITU G.726 PLC ? Specially handling of the encoder-
decoder state tracking during the packet loss?
Any help ---most welcomed.

Hi
One scheme little complex but applicable for all non plc-lbr codecs:
--> decoder side need to keep run dummy encoder -and use either { G711
Annex-2 Plc
or - some lpc based -advanced scheme } to conceal the dropped packets.
--> do encode the concealed packets with pre- trained encoder at decoder
side
and provide it to Decoder.
