Abstract

Abstract:

Usually, a multiple-input multiple-output (MIMO) system needs to deploy more than two leaky coaxial cables (LCXs). A $2\times 2$ MIMO system using a single LCX as transmitters was measured. Signals are fed from both ends of the LCX port separately, which can be used as two antennas. The results show that the performance of a single LCX system is close to that with two LCXs, and is much better than a single-input single-output system. The conclusion provides a reference for the design of LTE-M private communication networks.

Key words: leaky coaxial cable (LCX), long term evolation-metro (LTE-M), multiple input multiple output (MIMO), channel capacity, telecommunication system
