(32,10) 2nd order reed muller code generation

Started by ckkumar April 3, 2007
Hi,

Can some one please tell me how (32,10) subcode of 2nd order reed muller
code is derived. I need to understand the coding theory behind this code
as its used in Layer 1 UMTS 3GPP 25.212 specification to encode TFCI. What
are its special properties and why this code was choosen for TFCI encoding.
It would be of great help if someone can give me technical papers published
on the same.

Regards

Kiran

Kiran, This is a good document to get you started. http://www.3gpp.org/ftp/tsg_ran/WG1_RL1/TSGR1_06/Docs/Pdfs/r1-99913.pdf It talks about the basis of using FHT correlators for decoding the bi-orthogonal first order RM codes. And then how to update the decoding algorithm for this modified RM code. It also talks about the weight distribution of the code which has all the information on the coding gain. To play with more error correcting codes and the FHT algorithm you can go to http://signals.thingsconnect.com/ Hope this helps Sele _____________________________________ Do you know a company who employs DSP engineers?
