摘要：
In this paper, we propose a new scheme to improve the performance of Space-Time Block Coding in OFDM Systems. In this scheme, the optimization adaptive transmit beamformimg is used based on channel state information. And, the optimization beamforming weight vector is derived in case of maximal receiver signal-to-noise ratio. Theory analysis and computer simulation results of the system over frequency selective fading channels show that our proposal system can significantly outperforms the traditional STBC-OFDM systems, especially over fast fading channels.
