Soft decision decoderReed Solomon implementation

Started by reedsolomon May 16, 2006
Hi,

Is anyone out there aware of any implementations (C/MATLAB) of Soft
Decision Decoding for Reed Solomon, that I could use for research work?

Thanks alot
RS.

I would figure that some one named Reed Solomon would already know what is out there about RS codes ;-)
That is the IRONY....
It seems like there are no publically available implementations of SDD for
RS codes. :-(

There are some articles on soft-decision decoding of Reed-Solomon
codes.  A search on IEEEXplore will give you at least 10 or so.  I
don't know if the researchers have implemented the algorithms, but I
suspect they did.

I have read most of the papers from the IEEEXplore weblink, but as you have
mentioned there seems to be no implementations for these algorithms. 
Well it seems like it is time to implement one myself :(

Worked pretty well, but your RS code can't have too many parity symbols or the trellis would get too big. Unfortunately, I don't remember where that code is, and even if I still had it, I probably couldn't give it to you. Ray
