Analysis of hybrid ARQ in 3GPP LTE systems
, 2010 The use of Hybrid ARQ in wireless networks is to provide fast re-transmits and to lower the overall error rate. The performance of HARQ schemes is a well studied field, with many results to draw from in the literature.

Adaptive Turbo-Coded Hybrid-ARQ in OFDM Systems over Gaussian and Fading Channels
Journal of Communications Software and Systems, 2006 In this paper, an analytical approach for spectral efficiency maximization of coded wideband transmissions is presented based on OFDM. The approach exploits Type-III Hybrid-ARQ, enabling all sub-carriers to be employed in codeword transmission regardless

Hybrid-ARQ based intra-cluster geographic relaying
, 2004 This paper ∗ presents an integrated, cross-layer protocol that utilizes position location (e.g. through an onboard GPS receiver) and jointly performs the operations of physicallayer cooperative diversity, hybrid-ARQ retransmission, and relaying/routing ...

On Rate-Compatible Punctured Turbo Codes Design
EURASIP Journal on Advances in Signal Processing, 2005 We propose and compare some design criteria for the search of good systematic rate-compatible punctured turbo code (RCPTC) families. The considerations presented by S. Benedetto et al.

Performance of ATM networks under hybrid ARQ/FEC error controlscheme [PDF]
, 1999 In ATM networks, fixed-length cells are transmitted. A cell may be discarded during the transmission due to buffer overflow or detection of errors. Cell discarding seriously degrades transmission quality.

Adaptive Turbo-Coded Hybrid-ARQ in OFDM
, 2008 In this paper, the performance of an adaptivemodulated and adaptive-rate hybrid automatic-repeat-request (Hybrid-ARQ) scheme is proposed for wideband communications based on an orthogonal frequency division multiplexing (OFDM).
