摘要 为了抑制多用户MIMO-OFDM系统的共道干扰,采用MMSE干扰抑制和符号估计相结合的检测方案,该检测方案接收端译码简单.理论分析及仿真结果表明,与传统检测方案相比,该检测方案在没有增加计算复杂度的情况下有效地抑制并消除了共道用户干扰. In order to restrain the interference of co-channel users in MIMO-OFDM system,in this paper,adopted the combination of the detection scheme about the linear MMSE interference suppression and symbol estimation,and the receiver maintained decoding simplicity.Theory analysis and simulation results reveal that the proposed scheme can suppress and cancel the interference from co-channel users effectively without increasing the complexity significantly.
