Hi Shriram,
Do you need to perform errors-and-erasures decoding, or erasures-only
decoding?
Erasures-only decoding is a very simple process, which normally relies
on solving a set of equations (which can be done by inverting some
square matrix). With erasures-only decoding, you do not need to
calculate the erasure polynomial, or use Forney's algorithm.

Are you saying you can't find the error values even though
the polynomials are correct?
Start by debugging a really simple example, like the one-error case.
Once that works it should not be too difficult to get the whole
thing to work.

Hell All,
Can somebody Please provide me with a reliable source for studding and
implementing a Reed Solomon Decoder capable of correcting Erasures?
I have already implemented the syndrome detector, the Erasure
Polynomial, Berlekamp � Massey Algorithm and the program (written in C
using VC++) is capable of finding the correct error / erasure locator
polynomial but for some reason the (Modified) Forney Algorithm does
not work. I need a good source (and lot of examples) to study Forney
Algorithm and implemented.

Shriram
