Thank you Marcus.

I've checked out gr-fec. The problem is that Decode CCSDS 27 block takes float input while my data to feed it is in byte.

If you've built the documentation of the latest version of GNU Radio, look at the Forward Error Correction page for a description of the new FEC API. It's designed with exactly your issue in mind. You would write a new deployment for the FEC of your choice to handle the data type conversions. In fact, the current CC decoder actually takes in bytes but the deployment takes in floats. The floats are intended to be soft symbols, and the decoder deployment converts from the soft symbol floats to a quantized soft symbol byte that floats at a particular level.

Hi Hoang,

GNU Radio 3.7 has the gr-fec framework, and recent updates brought more performance and some features, so if that matches your use case, go ahead and try it out!

Greetings,
Marcus

Deal all,

Does anyone update the Channel Coding (https://www.cgran.org/wiki/chancoding)
toolbox so that it can work in Gnuradio 3.7.0?

I did try to install this toolbox. The installation was done but it do not
appear in Gnuradio Companion interface.

Thanks,
Hoang
