摘要：
In this paper, we describe several techniques for the analysis and design of OFDM multiple-antenna systems, which include channel estimation and tracking, optimal training sequences for initial channel acquisition, and adaptive power allocation with closed-loop updating of channel state information for capacity improvement.
