Re: [Discuss-gnuradio] Reed-Solomon en/decoder

[Jeon]

Thanks, Ron and Tom.

But I couldn't find atsc_rs_encoder_impl.cc. Only I can find decoder.

I'm using version 3.7.6.1

One thing is, I can find rs en/decoder in gnuradio/gr-atsc.

Are these irrelevant with gr-dtv?

When I look into repository, gr-dtv/lib/ has both encoder and decoder

Currently, I am installing the newer version.

Reagrds,

Jeon.

Take a look in:

I need Reed-Solomon encoder and decoder to perform RS(15, 2/4/7/11).

I found that there are RS codes in gr-fec/lib/reed-solomon.

But, I couldn't find some grc blocks implementing the library codes.

In addition, I don't see work() function which is generally implemented in other blocks.

On the other hand, I found ccsds keyword in decode_rs_ccsds.c and encode_rs_ccsds.c

and I can find that keyword in some grc blocks, fec_encode_ccsds, fec_decode_ccsds, ccsds_encoder_def.

But, I don't think such blocks can do what I want.

Are there encoder and decoder which have been already implemented?

Do I not understand how to use RS blocks which have been already implemented?

Or should I implement them?

Regards,

Jeon.

What Ron points out will probably get you going fastest. The FEC API doesn't yet fully support the structure needed for RS coding schemes, though it's on the to-do list.
