RE: [ecc] reed solomon

Sir,

There are some things which I need clarified (using the Forney Algorithm),
and it would really be great if you can help me with this :

1. when you perform [1 + S(x)]L(x), this will give you a polynomial of
degree 2t^2, when you do mod^(2t + 1), is this just a matter of eliminating
all polynomials with coefficients greater than or equal to (2t + 1)?
2. what is the significance of the negative sign in computing the magnitude
using the formula :
	e = -Xk Omega
	    Lambda prime

I've finished designing the error locations block, and it works fine.
However, I can't seem to make the error magnitudes block work.
Thank you very much in advance!

Hi!

My project also include a Reed Solomon Codec .... the decoding core is
implemented in SystemC ... can you send me more details about your problems
?

Hi! My current project involvement is the design of a (255,223) Reed Solomon
CODEC. I've implemented it using the Chien Search & Forney Algorithm.
However I am having some problems with the decoding process. Is there anyone
who can help me? Thank you very much.
