摘要 提出了一种基于信道特性的自适应发送波束成形空时分组码正交频分复用(STBC-OFDM)系统方案.给出了最大接收信噪比条件下最优发射权值的闭式解和性能仿真结果.该系统能最大限度地利用所有的分集资源并对发射功率进行最优分配.与传统的STBC-OFDM系统相比,系统性能有明显的提高,而与系统较复杂的空时格码OFDM系统和TCM-STBC-OFDM系统相比,在高信噪比条件下能获得较大信噪比增益.讨论了存在信道估计偏差时,自适应发送波束成形STBC-OFDM系统的性能. An adaptive transmitting optimization beam-forming space time block coding-orthogonal frequency division multiplex （STBC-OFDM） system, called adaptive beamforming STBC-OFDM （ABF-STBC-OFDM） system based on channel state information （CSI）, was proposed. And the optimization beam-forming weight vector was derived in case of maximal receiver signal-to-noise ratio. The performance of ABF-STBC-OFDM system when there are channel estimation errors was given. Performance and computer simulation results of the system over wireless Reyleigh fading channels show that all the diversity resource can explored by the system, and the performance of the system can be improved significantly when compared with STBC-OFDM, space-time trellis coding-OFDM（STTC-OFDM） and trellis code modulation-STBC-OFDM （TCM-STBC-OFDM） system.
