This paper introduces a 2-by-2 multi-input multi-output (MIMO) system employing a single leaky coaxial (LCX) cable with signals inputted from its both sides. We measured the throughput of 2-by-2 LCX-MIMO system in a linear corridor environment under IEEE802.11 standard in 5GHz band. From the results, the proposed system using single LCX cable can achieve the MIMO transmission. The results also illustrated that the proposed system with LCX cable placing at high position shows better performance than that of the system with LCX cable placing on the floor.
