Joint Network and LDPC Coding for Bi-directional Relaying
نویسندگان
چکیده
In this paper, we consider joint network and LDPC coding for practically implementing the denosie-and-forward protocol over bi-directional relaying. the closed-form expressions for computing the log-likelihood ratios of the network-coded codewords have been derived for both real and complex multipleaccess channels. It is revealed that the equivalent channel observed at the relay is an asymmetrical channel, where the channel input is the XOR form of the two source nodes.

Joint physical network coding and LDPC decoding for two way wireless relaying
In this paper, we investigate the joint design of channel and network coding in bidirectional relaying systems and propose a combined low complexity physical network coding and LDPC decoding scheme. For the same LDPC codes employed at both source nodes, we show that the relay can decode the network coded codewords from the superimposed signal received from the BPSK-modulated multiple-access cha...
متن کاملBi-directional half-duplex protocols with multiple relays
In a bi-directional relay channel, two nodes wish to exchange independent messages over a shared wireless half-duplex channel with the help of relays. Recent work has considered information theoretic limits of the bi-directional relay channel with a single relay. In this work we consider bi-directional relaying with multiple relays. We derive achievable rate regions and outer bounds for half-du...
متن کاملNoncoherent LDPC-Coded Physical-Layer Network Coding using Multitone FSK
A noncoherent two-way relaying system is developed using physical-layer network coding for improved throughput over conventional relaying in a fading channel. Energyefficient noncoherent operation is achieved using multitone frequency shift keying (FSK). A novel soft-output demodulator is developed for the relay, and corresponding achievable exchange rates are found for Rayleigh fading and AWGN...
متن کاملMultiantenna Analog Network Coding for Multihop Wireless Networks
This paper proposes a minimummean-square-error bi-directional amplify-and-forward (MMSEBAF) relaying protocol for multi-hop wireless networks employing multi-antenna relays. MMSEBAF is a two-phase relaying protocol which allows for two sources to exchange independent messages via a relay node equiped with multiple antennas. The latter performs a joint linear MMSE filtering of the received signa...
متن کاملAchieving Capacity of Bi-Directional Tandem Collision Network by Joint Medium-Access Control and Channel-Network Coding
In ALOHA-type packetized network, the transmission times of packets follow a stochastic process. In this paper, we advocate a deterministic approach for channel multiple-access. Each user is statically assigned a periodic protocol signal, which takes value either zero or one, and transmit packets whenever the value of the protocol signal is equal to one. On top of this multiple-access protocol,...
