Exploiting Dimensions Of The Mimo Wireless Channel: Multidimensional Link Adaptation

In this paper, we propose an adaptive radio interface scheme for systems that employ multiple antennas. This is in contrast to the adaptive interface of single-antenna systems like in current packet data cellular systems. We propose groups of transmission parameters called Modulation, Coding and Antenna Schemes (MCAS) that are chosen according to the current conditions of the wireless channel, in order to maximize the performance in terms of goodput, while maintaining a certain level of reliability. © 2005 IEEE.612924928Tarokh, V., Jafarkhani, H., Calderbank, A.R., Space-time block codes from orthogonal designs (1999) IEEE Transactions on Information Theory, 5, pp. 1456-1467. , JulZheng, L., Tse, D., Diversity and multiplexing: A fundamental tradeoff in multiple antenna channels (2003) IEEE Transactions on Information Theory, 49, pp. 1073-1096. , MayDe Almeida, A.L.F., Freitas Jr., W.C., Cavalcanti, F.R.P., Mota, J.C.M., De Lacerda Neto, R.L., Performance of a MIMO systems with a hybrid of transmit diversity and spatial multiplexing (2003) XX Simpósio Brasileiro de Telecomunicações (SBrT), , Rio de Janeiro-RJ, BrasilAlamouti, S., A simple transmit diversity technique for wireless communications (1998) IEEE Journal of Selected Areas in Communications, 16, pp. 1451-1458. , OctFoschini, G.J., Gans, M.J., On limits of wireless communications in a fading environment when using multiple antennas (1998) Wireless Personal Communications, 6 (3), pp. 311-335. , MarHaykin, S., (1996) Adaptive Filter Theory, , Prentice-HallVucetic, B., Yuan, J., (2003) Space-time Coding, , Wile
