The benefits of MIMO technology are obtained through a combination of antenna arrays that can provide spatial diversity and algorithms that can adapt to the propagation channel. Antenna arrays have to be designed to be robust in different propagation scenarios and provide the degrees of spatial diversity expected by the algorithms. The algorithms can adaptively reconfigure the transmission methods by tracking the changing channel conditions. The premise of the work presented in this dissertation is that antenna arrays and algorithms at the physical layer can be designed, based on performance metrics from different layers, to exploit the channel spatial selectivity, resulting in improved system performance.(6.15) 6.2.2 Zero-Forcing Receivers (BICM-ZF) We have previously derived the LLC for BICM-ZF in i.i.d. Rayleigh channels as ... Substituting the conditional p.d.f. (6.12) into (6.15), using (6.10), and averaging over u and a a Aiu we obtain Ntanbsp;...
