Type-II hybrid ARQ protocol using concatenated codes
G. Benelli, Andrea Garzelli · IEE Proceedings I Communications Speech and Vision · 1993
The high throughput achieved by type-II hybrid automatic repeat request (ARQ) protocols can be enhanced by using the inner structure of a codeword in a concatenated coding scheme. The paper presents a new type-II hybrid scheme based on concatenated codes to which two retransmission strategies have been applied. The results on throughput bounds show that the proposed protocols are effective even in the case of communication channels with high error rates.
