Regarding my previous message -- it works if I put the generator poly in the rsenc function. But I have a problem with the decoder. Again, I am using the following simple matlab code to test it and show my problem. The code does not seems to correct errors. In fact,I do not understand how...
Thanks. Actually, I tried the following matlab RS code (also see the attachment) based on the 802.16d spec (see later), and could not get the same result as on page 444 of 802.16d spec:
%test data (36 bytes), page 444 of 802.16d spec...
802.16d reed solomon
on the page 444 of 802.16d, there are some test data about encoding:
Modulation Mode: QPSK, rate 3/4, Symbol Number within burst: 1, UIUC: 7, BSID: 1, Frame Number 1 (decimal values)
Input Data (Hex)

reed solomon code tutorial
Can anybody recommend a link to a good reed-solomon decoder tutorial or a good explanation of how the decoder algorithm works (Berlekamp, Forney, etc.). Thanks a lot.
Regards.
