Title
Capacity of 4-by-4 MIMO Channel Using One Composite Leaky Coaxial Cable With User Position Information
Abstract
Leaky coaxial cable (LCX) is applied broadly for many application scenarios because it can be utilized as antenna for user localization, wireless power transfer (WPT) and wireless coverage. Usually, one LCX can be used as one antenna, and therefore more cables are required for the configuration of an multiple-input and multiple-output (MIMO) system. This paper will provide a simple design that a 4-by-4 MIMO channel can be realized with one composite cable. Therefore the proposal can release the space limitation for MIMO deployment. The results show that, over 5 GHz frequency band, even though the distance between two V-type LCXs is 2 cm, the proposed 4-by-4 LCX-MIMO can have good channel condition which ensures the proposed composite cable can be made as a finer one. In addition, using user's position information (PI), we propose a simple power allocation scheme for the proposed LCX-MIMO system. Compared with the allocation method of equal power, the proposed method using PI can largely improve its capacity with the same level of computational complexity and without requirement of the feedback of channel status information (CSI).
