This article reviews space-time modem technology for mobile radio applications. We begin with motivations for the use of space-time modems and then brieey discuss the challenges posed by wireless propagation. Next, we develop a signal model for the wireless environment. Channel estimation, equalization , and ltering techniques for space-time modems in the forward and reverse links are then discussed. Finally we review applications of space-time modems to cellular systems and discuss industry… CONTINUE READING
