摘　　要：提出了基于多用户MIMO-OFDM和多用户=MISO- OFDM的两种信号传输预处理技术方案,构建了两方案的系统模型,并依据系统模型推导出了数据发送及检测算法。两方案均可大大降低移动终端的数据检测复杂度。通过在TDD系统应用环境中的仿真,比较了两方案与预瑞克的系统误比特率性能,表明多用户信号传输预处理技术方案有更好的系统误比特率性能。Two schemes of signal transmitprocessing（STP） technology based on multi-user MIMOOFDM and multi-user MISO-O？DM were proposed. System models were builded, and the algorithm of the data transmission and detection were developed according as these models. The receiver＇s calculative cost was reduced with these schemes. The results of the simulation in the TDD system were presented, which indicated the Bit Error Rate （BER） of the multi-user STP was more less than that of the Pre-Rake.
