摘要
在这项工作中，我们提出了一种统一的阿拉穆蒂码单载波时空码分多址分组传输系统框架。该系统利用多天线和多径分量作为冗余信息，产生具有全分集增益的方案，G d = n T L，其中n T为天线数，L为传输中的多径分量数。该系统允许我们利用Alamouti码的正交特性，并对每个发送符号分别解码，从而降低了计算复杂度。
Space-Time Coding for Single Carrier Block CDMA Systems
—In this work we propose a unified framework for single carrier space-time CDMA block transmission systems with Alamouti’s code. The proposed system uses the multiantenna and multipath components as redundant information to produce schemes with full diversity gain, G d = n T L , where n T is the number of antennas and L is the number of multipath components in the transmission. The proposed system allow us to exploit the orthogonal property of Alamouti’s code and to decode each transmit symbol separately, thus, reducing the computational complexity.
