Adaptive Hybrid-ARQ Scheme Based on Rate Estimation Technique for Rate-Compatible LDPC Codes
Tetsuo Tsujioka, Mami Tsuji (Osaka City Univ.) CS2007-68
Abstract (in Japanese) (See Japanese page) 
(in English) Rate-compatible LDPC (RC-LDPC) codes have a great attention because of their flexibility and easy to provide various performances by changing the number of parity blocks.
The authors have been considered several blind estimation techniques based on likelihood information of the sum-product decoder and achieved the performance analysis.

In this paper, the authors made performance evaluation on throughput of rate estimation where transmission code is selected adaptively to maximize throughput in Hybrid-ARQ scheme.
The performance analysis is made by computer simulations.
RC-LDPC codes with information bits of 768, 1536, 3072 and 6144 are used for evaluation.
It can be obtained that the proposed rate estimation has good performance
where Hybrid-ARQ scheme with incremental redundancy technique is employed.
