摘要 针对超3代(B3G)系统中广义分布式天线阵的架构,提出了适用于多个多天线阵中多输入多输出(MIMO)结构的交叉迭代检测译码算法.该算法通过在多天线阵之间交叉传递信息的方式,将传统的贝尔实验室分层空时码(BLAST)译码算法与干扰删除操作结合起来,实现交叉迭代译码,有效地解决了广义分布式天线阵系统中相邻天线阵覆盖范围内使用相同资源用户之间的干扰问题,改善了系统性能. An improved cross-interference iterative decoding algorithm for multiple input multiple output（MIMO） structure was proposed to reduce the interference among users employing the same resource in generalized distributed antenna array architecture of beyond 3G（B3G） system. The traditional decoding algorithm for Bell lab layered space time （BLAST） code and interference cancellation by transferring information among multi-antenna arrays were combined. The iterative decoding process was performed for several times, which would solve the problem of interference among users in adjacent coverage areas of antenna arrays and improve the performance of the system effectively.
