Design of MIMO Antenna Array Architecture for Higher Channel Capacity
In many extensive researches, the channel capacity of narrowband multiple-input multiple-output (MIMO) communication systems in indoor Line-of-Sight (LOS) environment is investigated and proved that the LOS signal can get the high channel capacity by designing the antenna arrays. On the other hand, MIMO systems offer significant capacity enhancements in non Line-of-Sight (LOS) environments where rich scattering is present. However, the wireless propagation mechanisms and antenna array orientation should be considered when designing the wireless network to get more precise results and improve the performance. This paper investigates the performance of MIMO system based on two ray ground reflection model. In this system, the LOS signal and the LOS signal with one ground reflected ray can provide the optimum MIMO capacity performance if specific designed antenna arrays are employed at both sides of the communications link. For achieving the optimal MIMO capacity in a LOS environment, the antenna array architecture is considered as a function of the distance between transmitter and receiver, the transmitted and received antennas’ height, the array orientation and the antenna spacing distance. The capacity sensitivity for a number of MIMO architectures with respect to the experimental data and simulation is investigated by using MATLAB programming language.
