摘要 在现有超空时编码技术基础上,提出了一种三维正交编码,文中称之为超正交空时极化编码方案。该技术在提供有效的编码增益的同时,保证了全额的空间与极化联合分集增益。对使用双极化天线的MIMO系统,还可以保证在达到系统所需求的误码特性和传输速率的同时,大大降低系统的天线数目。仿真结果表明在双极化天线MIMO传统中,文中提出的方案比采用超正交空时网格二维编码方案能提供更大的编码增益。 In this paper, we propose a super orthogonal coding scheme in joint space-time-polarization space. It combines set partitioning with a super set of orthogonal space-time-polarization block codes to provide full space and polarization diversity with improved coding gain. Simulations show that the proposed coding scheme outperforms the traditional super orthogonal space-time trellis coding space diversity approach.
