Space-time processing adds a new dimension to OFDM that can dramatically enhance some key operational parameters in a wireless network. In this chapter, we discuss the basics of beamforming, space-time coding, the capacity of a MIMO system, and the use of STC/beamforming in OFDM systems. The activities in this area have led to many exciting breakthroughs, some of which have already been adopted into new wireless standards such as the WiFi and the WiMAX.
