This article focuses largely on the receive (mobile - to - base station) time - division multiple access (TDMA) (non spread modulation) application for high - mobility networks. We describe a large (macro) cell propagation channel and discuss different physical effects such as path loss, fading delay spread, angle spread, and Doppler spread. We also develop a signal model incorporating channel effects. Both forward - link (transmit) and reverse - link (receive) channels are considered and the relationship between the two is discussed. Single - and multiuser models are treated for four important space - time processing problems, and the underlying spatial and temporal structure are discussed as are different algorithmic approaches to reverse link space-time professing with blind and nonblind methods for single - and multiple - user cases. We cover forward-link space - time algorithms and we outline methods for estimation of multipath parameters. We also discuss applications of space - time processing to CDMA, applications of space - time techniques to current cellular systems, and industry trends.
