Interleaving Gains for Receive Diversity Schemes of Distributed Turbo Codes in Wireless Half–Duplex Relay Channels
This paper proposes the interleaving gain in two different distributed turbo-coding schemes: Distributed Turbo Codes (DTC) and Distributed Multiple Turbo Codes (DMTC) for half-duplex relay system as an extension of our previous work on turbo coding interleaver design for direct communication channel. For these schemes with half-duplex constraint, the source node transmits its information with t...
متن کاملPerformance Analysis of Protograph LDPC Codes for Nakagami-$m$ Fading Relay Channels
In this paper, we investigate the error performance of the protograph (LDPC) codes over Nakagamim fading relay channels. We first calculate the decoding thresholds of the protograph codes over such channels with different fading depths (i.e., different values of m) by exploiting the modified protograph extrinsic information transfer (PEXIT) algorithm. Furthermore, based on the PEXIT analysis an...
متن کاملPerformance analysis of protograph low-density parity-check codes for nakagami-m fading relay channels
In this study, the authors investigate the error performance of the protograph (low-density parity check) codes over Nakagami-m fading relay channels. The authors first calculate the decoding thresholds of the protograph codes over such channels with different fading depths (i.e. different values of m) by exploiting the modified protograph extrinsic information transfer (PEXIT) algorithm. Furth...
متن کاملAchievable Rates Of Half-Duplex Relay Networks
This paper discusses two coding approaches for a network of half-duplex relay terminals and presents achievable rates for the discrete memoryless relay channel. Both proposals gain on an implicit (in case of compress-and-forward) or explicit (in case of decode-and-forward) inter-relay cooperation.
متن کاملOn Gaussian Half-Duplex Relay Networks
This paper considers Gaussian relay networks where a source transmits a message to a sink terminal with the help of one or more relay nodes. The relays work in half-duplex mode, in the sense that they can not transmit and receive at the same time. For the case of one relay, the generalized Degrees-of-Freedom is characterized first and then it is shown that capacity can be achieved to within a c...
