Dear all,

I am searching a matlab source for *Sum Product Decoding Algorithm of Repeat
Accumulate Code.
*I would be grateful if anybody can provide me the source.

Recently I find the following link in Google Answer for the Code

There are several links below about LDPC, but the [1] is the best(it
has a PDF doc and deal with SPA). You may read "Efficient
Implementations of the Sum-Product Algorithm for Decoding LDPC" to
understand the [1]'s code. You may find it in scholar.google.com.

Matlab codes on LDPC:
[1]Low Density Parity Check Codes
http://www.lrz-muenchen.de/~prasanna/ldpc.htm
<http://www.lrz-muenchen.de/%7Eprasanna/ldpc.htm>

Unfortunately I can't find any source from above link.
If anybody has this source, this may be of  my great help.

Any suggestion is welcome

regards

Arijit
