dexter gerrit-no-reply at lists.osmocom.orgdexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmocore/+/17326 ) Change subject: conv: add convolutional coder for AMR SID UPDATE frames ...................................................................... conv: add convolutional coder for AMR SID UPDATE frames AMR SID update frames are protected using an 1/4 convolutional coder, wich is similar to the one used with 6,7 kbit voice frames. Except that there is no puncturing and the length is differen.
