Dear friends, i am working on EFR compatible AMR. In one of the documents presented at 3gpp meeting by Ericsson i find the following statement: "AMR 12.2 has 5 ms longer delay than GSM EFR which is caused by the (dummy) look-ahead of 5 ms (added to allow seamless frame-wise mode switching with the rest of the AMR modes)" I am not finding that how and where this delay is introduced in AMR 12.2k implementation. i am not also finding any reference to this look-ahead delay in standard AMR documents. Could you please help me by giving me some reference. Thanks, yours sincerely, manoj |
