DESIGN OF MIMO SYSTEM WITH UNIFORM CIRCULAR ARRAY OVER LOS CHANNEL AND DESIGNING APPARATUS AND METHOD THEREOF

摘要

Proposed are a multi-input multi-output (MIMO) system using a circular array in a line of sight (LOS) channel environment, an apparatus for designing the MIMO system, and a method for designing the MIMO system. According to an embodiment of the present invention, the method for designing an MIMO system using a circular array in a LOS channel environment comprises the steps of: calculating a channel coefficient of the circular array; estimating a channel matrix of the circular array by converting the channel coefficient into a determinant; and obtaining an optimal radius of the circular array for obtaining the maximum channel capacity in the channel matrix, wherein the optimal radius can obtain the maximum frequency efficiency in the LOS channel.
