Re: [Discuss-gnuradio] Convolutional decoder

[Dan CaJacob]

Use the FEC Extended Encoder/Decoder with the CC Encoder/Decoder definition blocks. This assumes you are implementing a continuous modulation, like the CCSDS standard and not a bursty system.

Hello everybody,

 

I am looking for a convolutional decoder for my ground station. I have found the ccsds 27 which does the 1/2 code rate. Unfortunately I would like to have ¾ code rate.

I found the cc decoder definition with the FEC extended decoder. In documentation, it is written that it cannot operate with another code rate than ½.

 

Do I misunderstood something or is there any generic “like” convolutional decoder that I can use for my purpose?

 

Thanks a lot

 

Sam
