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.
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 demon- strate the efficient ability of the proposed receiver in multi-path fading channels.
