Moreover, for ease of mathematical tractability, channels considered in such studies are generally assumed to be subject to Rayleigh fading or to be Nakagami-$m$ channels with integer fading parameters, which is impractical in typical urban environments. In this paper, we propose a unified moments-based framework for general performance analysis of channel-state-information (CSI) assisted amplify-and-forward (AF) relaying systems. The framework is applicable to both one-way and two-way relaying over arbitrary Nakagami-$m$ fading channels, and it includes previously reported results as special cases. Specifically, the mathematical framework is firstly developed under the umbrella of the weighted harmonic mean of two Gamma-distributed variables in conjunction with the theory of Pad\'e approximants. Then, general expressions for the received signal-to-noise ratios of the users in one-way/two-way relaying systems and the corresponding moments, moment generation function, and cumulative density function are established. Subsequently, the mathematical framework is applied to analyze, compare, and gain insights into system performance of one-way and two-way relaying techniques, in terms of outage probability, average symbol error probability, and achievable data rate. All analytical results are corroborated by simulation results as well as previously reported results whenever available, and they are shown to be efficient tools to evaluate and compare system performance of one-way and two-way relaying. dc.language.iso en dc.publisher Institute of Electrical and Electronics Engineers (IEEE) dc.relation.url http://ieeexplore.ieee.org/lpdocs/epic03/wrapper.htm?arnumber=6280252 dc.rights Archived with thanks to IEEE Journal on Selected Areas in Communications dc.title Moments Based Framework for Performance Analysis of One-Way/Two-Way CSI-Assisted AF Relaying dc.type Article dc.contributor.department Communication Theory Lab dc.contributor.department Computer, Electrical and Mathematical Sciences and Engineering (CEMSE) Division dc.contributor.department Physical Science and Engineering (PSE) Division dc.identifier.journal IEEE Journal on Selected Areas in Communications dc.eprint.version Post-print dc.contributor.institution Institut National de la Recherche Scientifique (INRS), University of Quebec, Montreal, QC, Canada dc.contributor.affiliation King Abdullah University of Science and Technology (KAUST) kaust.person Xia, Minghua refterms.dateFOA 2018-06-13T13:55:03Z dc.date.published-online 2012-08-23 dc.date.published-print 2012-09
