Chains of cyclic codes, Construction X and incremental redundancy
Cen Jung Tjhai, M. Tomlinson, Markus Grassl · 2008
It is shown that chains of cyclic codes in conjunction with constructions X and XX can be used to efficiently construct sequences of linear codes for application in incremental redundancy communications. In addition to using a CRC for error detection, a novel CRC-less approach to error detection, which is based on the confidence level of the soft decision decoding output, is introduced. This novel approach provides an attractive trade-off between error rate performance and throughput for incremental redundancy communications.
