Re: CCSDS BCH and CLTU coding
Hi I have a couple of follow up questions: 1. What is the purpose of the "Acq_samples" and "CLTU's" arguments used by the block? 2. I installed the OOT module on gnuradio 3.7, but it looks like gnuradio fails to import the module and I'm receiving an import error "no module named kcsa_swig" . Do you know what I'm missing by any chance?

Re: CCSDS BCH and CLTU coding
CCSDS BCH(63,56) is a block code, take 7 bytes as input, 63bits as output. see details in ccsds 231 book.

Re: CCSDS BCH and CLTU coding
Yotam, You are probably missing swig, sudo apt-get install swig. Then after cmake, make, sudo make install, run ldconfig. - Brandon Smith On Wed, Nov 9, 2022 at 6:32 AM Yotam Rabin wrote: > Hi I have a couple of follow up questions: > 1.
