synchronisation test sequences for GSM speech codecs

Started by ksvd prasad May 14, 2002
Hi,
I'm facing some problem when i'm ensuring
bit/frame synchronisation test sequences for GSM
speech codecs(HR/EFR/AMR) as specified by the
standard. In the standard also they didn't specify how
to test it? if any body works on this please clarify
this point. By the way i think ETSI is not offering
free ANSI-C code software for (GSM-FR)full rate speech
codec. Is anybody providing free GSM-FR ANSI-C code
software?
thanks
prasad.



Prasad,

ETSI provides all the source code, documentation and test sequences as well.
For your reference I am sending you the ftp site where you can download the
above said and lot many.

Gopal
