Abstract
This article reviews space-time modem technology for mobile radio appl ications. We begin with motivations for the use of space-time modems a nd then briefly discuss the challenges posed by wireless propagation. Next, we develop a signal model for the wireless environment. Channel estimation, equalization, and filtering techniques for space-time mode ms in the forward and reverse links are then discussed. Finally, we re view applications of space-time modems to cellular systems and discuss industry trends.
