[M4IF Technotes] Error Recovery and Concealment at 10^(-3) BER

[Arvind Raman]

I am currently carrying out experiments on Error recovery and
concealment at Bit Error Rates (BERs) of 10^(-4) and 10^(-3). Though I
could good pretty good results at 10^(-4) with just a data partitioned
bitstream (without using RVLC), it doesn't really work well at BERs as
high as 10^(-3). I feel that the packet size (at a certain bitrate)
could play a crucial role in deciding how good the algorithm works at
such high BERs. 
I would thus like to know
1. What would be an ideal packet size to use, at BERs as high as 10^(-3)
for 64 kbps
2. Is it possible to error conceal a 10^(-3) BER affeted bitstream so as
to get no visual degradation. If so, is it possible only thru the use of
RVLCs.
Thanks a lot for your time and help.
