Design of optimal MIMO channel under line-of-sight environment by using directional antenna

Abstract

This paper presented the channel capacity improvement by the distributed antenna arrangement and directional antennas under LOS environment. The simulation results showed that the proposed system provided higher channel capacity than the centralized antenna system. From experimental results, the proposed system achieved low correlation and saved up to 84% of transmit power under indoor environment. The proposed system is expected to provide the optimal channel matrix to maximize the channel capacity by the use of high directivity l antenna.
