[Discuss-gnuradio] Problem of puncturing in the FEC Extended Tagged Encoder
Mon, 21 Jan 2019 18:41:26 +0100
I am using the FEC Extended Tagged Encoder block with a CC Encoder
Object. Everything is fine when there is no puncturing (meaning that P =
'11'). However when I want to add some puncturing, there is a problem of
tag. Indeed, the length tag is not updated depending on the puncturing
pattern. For example if my input stream is of "length=1000" and my
puncturing pattern is P='1101', the real output stream is of length 750
whereas the tag is still "length=1000".
I have some idea to fix this (for instance by adding a block just after
this one to modify the tag value). However, I think it could directly be
corrected in the original block.
I'm using GNU Radio Companion 220.127.116.11.
