【摘要】 本文介绍了一种基于极化天线阵列与V-BLAST算法结构的多输入－多输出（MIMO）无线链路的方案设计。根据其数学模型，分析了MIMO系统的信道容量，并与一些典型系统进行了对比。针对使用环境的限制与多径环境中电磁极化的特殊情况，提出了利用极化天线阵列构建MIMO系统的设计方案。给出了相应的天线阵列结构，通过计算机仿真与信道传输特性测试验证了使用极化天线阵列的可行性。论述了相应的信号处理算法。对涉及到的关键技术如天线阵列合并、符号抵消与检测顺序优化技术进行了理论分析。最后对系统的整体性能进行了分析讨论。更多还原

【Abstract】 A design method of a wireless MIMO link based on polarization antenna array & V-BLAST algorithm is presented in this paper. Compared with some typical systems, the results of channel capacity analysis of MIMO channel are given. Aimed at the confined condition in this system and the special polarization mode of electromagnetic field in multi-path environment, the architecture with polarization antenna array is proposed. The structure of the antenna array is given. Also, the feasibility of this structure is proved through computer simulation and channel transfer characteristic measurement. The relevant signal processing algorithm is discussed, with emphasis on the array combining, symbol cancellation, optimal detection ordering. Finally the overall performance is analyzed and discussed.更多还原
