Optimal degree distributions for LDPC codes

[sree1024]

Hello,

In my project, i am using regular ldpc codes. But for better performance i should go with Irregular ldpc codes.
people used to get optimized degree distributions for ldpc codes from the following site : LTHC: LdpcOpt but for the past 1 year it's not working,
If any of you guys know any alternative idea....plz suggest me


Thanks,
sree

Irregular codes though better in performance are not easy to implement, look at QC codes. In the case of performance you cna even look at fountain codes, spherical codes, ..you want to tune your coder to the application and relevance.
