Hi Jeon,
I don't think RS is typical only for DVB apps. RS is indeed used in DTV but it
has been used in many wireless applications before too as being simple to
implement and having many advantages as an block coder/decoder together with
convolutional one. One advantage of RS is its capability of recovering errors
that appear in bursts. This is why it has been used also in harddrives and
barcode readers where errors may appear in bursts and entire portion of the
data could be missing entirely.

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)

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?

Jeon.
