- W2188547188 abstract "Inthis papertheergodic mutualinformation ofthe i.i.d. Rayleigh fading amplify-and-forward MIMO relay channel without direct linkbetween source anddestination isderived inthelarge arraylimit. Bymeansofthereplica methodan expression isobtained, whoseparameters aredetermined bya nonlinear equation system. Thissystem canbesolved inclosed form.Comparisons withMonteCarlosimulations showthatthe asymptotic expression serves asanexcellent approximation for systems withonlyveryfewantennas ateachnode. I.INTRODUCTION Cooperative relaying hasobtained majorattention inthe wireless communications community inrecent yearsdueto itsvarious potentials regarding theenhancement ofdiversity, achievable rates andrange. Animportant milestone within the widescope ofthis field istheunderstanding ofthefundamental limits oftheMIMO relay channel. Suchachannel consists of asource, relay anddestination terminal, eachequipped with multiple antennas. Generally, there aredifferent waysofincluding relays in thetransmission between asource andadestination terminal. Mostcommonly relays areintroduced toeither decodethe noisysignal fromthesource oranother relay, tore-encode theinformation bits andtotransmit ittoanother relay (multi- hop)orthedestination terminal (two-hop). Ortherelay simply forwards alinearly modified version ofthenoisy signal. These relaying strategies arereferred toasdecode-and forward (DF) andamplify-and-forward" @default.
