Thank you all of you who have answered to my questions.
I am sorry for anwering too late.
I'll try as many solutions as you suggested
and will let you know how I will have implemented it.
Regards,
Jeon.

The polynomial in gr-dtv is G1 = 171 and G2 = 133. It is a 1/2 rate code
with puncturing to 2/3, 3/4, 5/6 and 7/8.

Thanks for your answers, Ron and Marcus.
I posted this question since my module is using both Reed Solomon (

And I saw that CC is extremely slower than RS. Thus, I posted this
question, but I made a question too short
Hi Jeon,
speed depends on your hardware and the implementation of the decoder.
As a rule of thumb: the more "generally applicable" a decoder is, the
slower it gets.
Jan wrote a set of highly SIMD-optimized decoders, but these are (pretty
common) special cases, so they don't cover all the cases tha
Made a mistake. The DVB-T receiver is not part of the 3.7.8 release.
It's a recent commit on the master branch (3.7.9git).

He benchmarked the IT++ decoder in last place.
IT++ = 2-3 Mbps
gr-trellis = 5 Mbps
Karn C = 7-8 Mbps
gr-dvbt = 39-40 Mbps
The gr-dvbt receiver is
I've measured time taken by convolutional decoding in gr-ieee802-11. The
module is using Punctured Convolutional Code class from IT++ library (

)
I've used chrono (chrono.h, chrono) to measure time taken. You can se
