“…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.…”

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.

Relay transmission has been incorporated in the 3rd Generation Partnership Project (3GPP) for Long-Term Evolution (LTE) Enhancements (LTE-Advanced, or LTE-A). To effectively harvest the performance gain introduced by the relay transmission, wireless network coding techniques can be adopted. In this paper, using a simple three-node cooperative relay channel model, based on the decode-and-forward protocol, we consider a few wireless network coding techniques which can be used in advanced cooperative communications to improve the transmission efficiency and enhance the system performance.

Abstract-This paper proposes a full-rate cooperative scheme adapted to the slow fading semi-orthogonal multiple access relay channel (MARC). It is assumed that the sources transmit on orthogonal channels and the relay is half duplex transmitting on the same channels as the one of the sources. The sources employ LDPC to encode their messages before transmitting them, while the relay uses a simple demodulate-and-forward strategy to transmit the combination of the received codewords. The presence of the relay does not affect the time-scheduling of the sources. Therefore, this scheme is backward compatible to existing noncooperative systems. In order to cancel the interference at the destination, we propose a joint network-channel decoder that uses maximum a posteriori (MAP) detection and channel decoding. Through numerical results, we show the benefits of joint network-channel decoder. We also show that the proposed scheme significantly outperforms, in terms of BER, the non-cooperative system as well as the classical relay-assisted orthogonal channel network and that it achieves the maximum code diversity.
