| 摘 要： | 针对编码分组空时块码(G-STBC)多入多出正交频分复用(MIMO-OFDM)系统,提出了一种联合MIMO检测和信道译码的迭代接收机,其中MIMO解调器采用基于软符号并行干扰消除(PIC)和瞬时最小均方误差(MMSE)滤波的软入软出MIMO检测算法,不仅适用于M-PSK调制,也适用于M-QAM调制.仿真验证了文中迭代接收机在多径衰落信道中的高效检测能力.

| Abstract: | An iterative receiver combining multiple-input multiple-output(MIMO) detection and channel decoding was proposed for coded group-wise space-time block coding(G-STBC) MIMO-orthogonal frequency division multiplexing(OFDM) systems.In the proposed receiver,a generalized MIMO detection algorithm based on soft interference cancellation and instantaneous MMSE filtering is proposed,which is applicable to the cases with not only M-PSK modulation but also M-QAM one.The simulations demonstrate the efficient ability of the proposed receiver in multi-path fading channels. |
