Joint Channel-Network Coding for the Gaussian Two-Way Two-Relay Network
New aspects arise when generalizing two-way relay network with one relay to two-way relay network with multiple relays. To study the essential features of the two-way multiple-relay network, we focus on the case of two relays in our work. The problem of how two terminals, equipped with multiple antennas, exchange messages with the help of two relays is studied. Five transmission strategies, nam...
متن کاملImproved Rate-Compatible Joint Network-Channel Code for the Two-Way Relay Channel
In [1] a rate-compatible joint network-channel code (JNCC) for the two-way relay channel was proposed which can be applied for the cooperative uplink and downlink in a mobile communication system with the help of a relay. We assume the system model of [1] and present an improved JNCC which is based on the decode-and-forward scheme of [2]. In [2] a coding scheme was proposed which does not consi...
متن کاملCompressed Channel Sensing for Two-way Relay Network
Two-way relay network (TWRN) was introduced to realize high-data rate transmission and to improve spatial diversity over the frequency-selective fading channel. However, channel state information (CSI) is needed due to the requirement from coherent data detection and the self-data removal at terminals. Traditional training-based linear probing techniques are able to achieve the accurate CSI by ...
متن کاملRelay Selection Based Space-Time Coding for Two-Way Wireless Relay Networks Using Digital Network Coding
In this paper, we propose a novel decode-and-forward dual-relay selection technique based on Alamouti space time coding for twoway wireless relay networks (TWRNs). The twoand the threephase TWRN protocol are used in the first and second version of the proposed technique, respectively, to exchange the information symbols of the communicating terminals. In order not to waste any power for transmi...
متن کاملRotationally Invariant Coded Modulation for Physical Layer Network Coding in Two-way Relay Fading Channel
This paper investigates a novel coded modulation scheme for Physical Layer Network Coding (PLNC) in the Two-Way Relay (TWR) fading channel. Using a fully-adaptive adaptive soft demodulator and Independent Decoding Levels, the proposed scheme can eliminate the effect of fading on the TWR Channel. To reduce system complexity at the relay, we also provide a low-complexity scheme with a series of f...
