Abstract
Leaky coaxial (LCX) cable is widely used in wireless communication systems as an antenna, especially for a long and narrow area called the linear-cell environment. The general usage of LCX cable is that it can be treated as one antenna. To configure a multiple-input–multiple-output (MIMO) system, it requires more than one LCX cable. In this paper, we propose a simple design in which one single LCX cable can be used as two antennas. Therefore, the proposal reduces the cost and spacing requirement and releases the space requirement of MIMO deployment for wireless application over linear-cell environments. We will study the capacity of the proposed LCX–MIMO system using equal power (EP) allocation and water-filling power allocation and compare its capacity with the conventional MIMO system using monopole antennas. The capacity results over the 2.4 GHz band and the 5 GHz band show that the proposed LCX–MIMO channel has better capacity than that of using monopole antennas over linear-cell environments. In particular, it can achieve more capacity improvement than that of channel using monopole antennas with the simple EP allocation. The throughput experiments over 5 GHz also show that our proposal can achieve the higher and stable throughput over the radiation coverage of LCX cable.
