摘要 针对垂直贝尔实验室分层空时(Vertical Bell labs layered space time,V-BLAST)结构的分布式MIMO系统,给出了一种基于后验信息迭代的软检测算法。该算法同时利用前一次迭代的后验信息与本次迭代的外信息计算发射符号的软信息。理论分析与仿真结果表明,该算法可加快迭代接收机的收敛速度,显著提升系统的整体性能。 针对垂直贝尔实验室分层空时(Vertical Bell labs layered space time,V-BLAST)结构的分布式MIMO系统,给出了一种基于后验信息迭代的软检测算法。该算法同时利用前一次迭代的后验信息与本次迭代的外信息计算发射符号的软信息。理论分析与仿真结果表明,该算法可加快迭代接收机的收敛速度,显著提升系统的整体性能。
