LDPC Code Design for Half-Duplex Decode-and-Forward Relaying
We propose LDPC code designs for the half-duplex relay channel. Our designs mimic the information theoretic random coding scheme for decode-and-forward relaying. An important advantage of our scheme is that it is built entirely of single-user codes that can be decoded by belief propagation. The optimization of relay LDPC code profiles presents unique challenges, which are met by using the densi...
متن کاملFull-Duplex Decode-and-Forward Relaying with Limited Self-Interference Cancellation
In this paper we address the transmit strategy design for a full-duplex (FD) one-way relaying system which operates in decode-and-forward (DF) mode. Our study starts with defining a system model which encompasses the limits of a FD system to overcome its own loopback self-interference. Afterwards we present a design strategy for the defined system focusing on the case with availability of the p...
متن کاملFull-Duplex Relaying with Half-Duplex Relays
We consider “virtual” full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multi-hop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage. With such a pipelined scheme, the source ...
متن کاملA Study of Half-Duplex Asymmetric Two-Way Decode-and-Forward Relaying Using Relay Selection
This paper examines the information theoretic metric of outage probability for a decode-and-forward (DF) based asymmetric two-way relay transmission (i.e. the two source terminals have different target rates). We first characterize the achievable rate region of a conventional three-node network. After that the conventional three-node scenario is analyzed in terms of outage probability and the c...
متن کاملRate, Reliability, and Delay Tradeoffs for Decode-and-Forward Relaying
We extend the random coding error exponent to three common decode-and-forward schemes for the relay channel. The resulting bounds give achievable tradeoffs among rate, reliability, and delay, allowing comparison of decode-and-forward with direct transmission and other schemes in broader terms than asymptotic achievable rates alone. In contrast to the asymptotic case in which the achievable rate...
