Abstract
The demand for robust and high data rate wireless transmissions in tunnel leads to evaluate the impact of MIMO and diversity techniques over the channel performance in these types of environments. This paper presents a 4×4 MIMO channel sounding measurement campaign performed in the tunnels of the FGC (Ferrocarrils de la Generalitat de Catalunya) metro in Barcelona, at 5.8 GHz. Different configurations were tested with different antenna polarization and orientation in the tunnel. From these measurements, MIMO channel matrices are computed, in order to determine the correlation level of the channel and the MIMO channel capacity along the tunnel.
对隧道中鲁棒和高数据速率无线传输的需求导致评估MIMO和分集技术对这些类型环境中信道性能的影响。本文介绍了在巴塞罗那FGC (Ferrocarrils de la Generalitat de Catalunya)地铁隧道中进行的4×4 MIMO信道测深活动，频率为5.8 GHz。在隧道中测试了不同天线极化和取向的不同配置。从这些测量中，计算MIMO信道矩阵，以确定信道的相关水平和MIMO信道沿隧道的容量。
