Abstract

Optimal multi-antenna wideband signaling schemes are derived for multipath channels assuming perfect channel state information at the transmitter. The scheme that minimizes the bit-error-probability in the single-user case is a rank-one space-time beamformer which focuses the signal transmission in the direction of the most dominant channel mode. Several sub-optimal variations are discussed for multiuser applications. Simulation results are given to compare the schemes proposed.

利用信道状态信息的最佳宽带发射天线分集

在假定发射机信道状态信息完美的情况下，推导了多径信道的最优多天线宽带信令方案。在单用户情况下，最小化误码率的方案是一阶空时波束形成器，该方案将信号聚焦在最优势信道模式的方向上传输。讨论了多用户应用程序的几个次优变量。仿真结果对所提方案进行了比较。
