“…Besides for point-to-point communication, the concept of rootchecks was also applied for relay channels [6], [7]. We show that our proposed LDPC code performs close to the information theoretical limit and outperforms the previous approaches in [3], [4] whose structures do not guarantee full-diversity.…”

“…H-ARQ systems with CPC were designed based on turbo codes [3] and on LDPC codes [4], but these code designs do not guarantee full-diversity, especially if the coding rate approaches the maximum coding rate yielding full-diversity.…”

Abstract-In wireless scenarios an effective protocol to increase the reliability for time-varying channels is the hybrid automatic repeat request (H-ARQ). The H-ARQ scheme with cross-packet channel coding (CPC) is a recently published extension of H-ARQ with several advantages. No full-diversity low-density paritycheck (LDPC) code design for the whole range of coding rates yielding full-diversity has been published. In this paper the authors provide a new outage behavior analysis and a new structured LDPC code ensemble achieving full-diversity for H-ARQ with CPC by exploiting the rootcheck principle. Simulation results show that the new code design outperforms the previous approaches, providing full-diversity and good coding gain, also at high coding rates.

“…In other words, the link-layer retransmissions are embedded in the next new packet's transmission, which avoids any potential throughput reduction imposed by retransmissions although naturally, they do impose additional interference. A similar idea was proposed in [12], which requires a specifically designed channel code and its application is limited to twin-packet joint transmissions. As a benefit, our proposed scheme is capable of jointly and simultaneously transmitting multiple packets and it is equally applicable to both Type I and II HARQ techniques.…”

Abstract-In this paper, we propose a novel superposition coding aided multiplexed Hybrid Automatic Repeat reQuest (HARQ) scheme for the sake of improving the link-layer transmission efficiency. The detailed system design is presented and the achievable link-layer packet error rate as well as the link-layer transmission efficiency metric is quantified. It is demonstrated that our scheme substantially improves the attainable transmission efficiency and it is particularly suitable for delay-sensitive services.

Abstract-In this paper, we propose a novel superposition coding aided multiplexed Hybrid Automatic Repeat reQuest (HARQ) scheme for the sake of improving both the link-layer and Transport Control Protocol (TCP) layer efficiency. The detailed system design is presented and the transmission efficiency metrics of both layers are discussed. Furthermore, the achievable linklayer packet error rate as well as a range of other transmission efficiency metrics of both layers are quantified. It is demonstrated that our scheme substantially improves the attainable transmission efficiency of both layers and it is particularly suitable for delay-sensitive services.
