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

[Jeon]

Thank you all Bogdan and Ron.

I wil try your codes.

It's not important, but one general question.

Why do the most of Reed-Solomon implentations exist under digital TV or broadcasting?

I can guess that DVB is the typical application of RS.

But, how about other wireless communications?

I can see a list of wireless applications with some googling. (I'm not sure they are standards or just proposal)

Regards,

Jeon.

HI Jeon, you might try the RS encoder/decoder in my gr-dvbt implementation. There are grc blocks that you can use directly after installing gr-dvbt.

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.
