Network Coding Based CQI Reporting for Two-Way Multi-Relay Networks
This paper considers channel quality indicator (CQI) reporting for data exchange in a two-way multi-relay network. We first propose an efficient CQI reporting scheme based on network coding, where two terminals are allowed to simultaneously estimate the CQI of the distant terminal-relay link without suffering from additional overhead. In addition, the transmission time for CQI feedback at the r...
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 کاملJoint 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 کاملEnergy-efficient resource allocation for OFDMA-based two-way relay channel with physical-layer network coding
Physical-layer network coding (PNC) is a novel cooperative technique for two-way relay channel (TRC), where two users exchange information via intermediate relay node(s). On the other hand, the issue of green communications to reduce energy consumption has recently started to arouse much attention. This article studies the energyefficient resource allocation problem for orthogonal frequency div...
متن کاملBounds for Multiple-Access Relay Channels with Feedback via Two-way Relay Channel
In this study, we introduce a new two-way relay channel and obtain an inner bound and an outer bound for the discrete and memoryless multiple access relay channels with receiver-source feedback via two-way relay channel in which end nodes exchange signals by a relay node. And we extend these results to the Gaussian case. By numerical computing, we show that our inner bound is the same with o...
