Low-complexity quantize-and-forward cooperative communication using two-way relaying
Cooperative communication is used as an effective measure against fading in wireless communication systems. In a classical one-way cooperative system, the relay needs as many orthogonal channels as the number of terminal it assists, yielding a poor spectral efficiency. Efficiency is improved in two-way relaying systems, where a relay simultaneously assists two terminals using only one timeslot....
متن کاملRate-Distortion Properties of Single-Layer Quantize-and-Forward for Two-Way Relaying
The Quantize & Forward (QF) scheme for two-way relaying is studied with a focus on its rate-distortion properties. A sum rate maximization problem is formulated and the associated quantizer optimization problem is investigated. An algorithm to approximately solve the problem is proposed. Under certain cases scalar quantizers maximize the sum rate. I. INTRODUCTION Consider a communication system...
متن کاملCompute-and-forward two-way relaying
In this paper, a new two-way relaying scheme based on compute-and-forward (CMF) framework and relay selection strategies is proposed, which provides a higher throughput than the conventional two-way relaying schemes. Two cases of relays with or without feedback transmission capability are considered. An upper bound on the computation rate of each relay is derived, and based on that, a lower bou...
متن کاملMulti-Cell Cooperation Using Subcarrier-Cooperative Two-Way Amplify-and-Forward Relaying
We consider two-way communication between multiple MIMO transceiver pairs that is assisted by non-regenerative half-duplex two-way relays. A generalized system model is formulated in which an arbitrary number of multi-antenna relays can make use of symbol extensions in frequency, e.g. OFDM subcarriers. In contrast to conventional approaches, the relays can forward arbitrary linear combinations ...
متن کاملCooperative Relaying at Finite SNR - Role of Quantize-Map-and-Forward
Quantize-Map-and-Forward (QMF) relaying hasbeen shown to achieve the optimal diversity-multiplexing trade-off (DMT) [1] for arbitrary slow fading full-duplex networks [2]as well as for the single-relay half-duplex network [3]. A keyreason for the DMT-optimality of QMF is that quantizing at thenoise level suffices to achieve the cut-set bound approximately towithin an add...
