We propose an antenna element arrangement suitable for self-interference reduction in short-range FD-MIMO(Full-Duplex Multi-Input Multi-Output) communication. In this report, we present an optimal antenna spacing offering an degenerated self-interference channel matrix, which is analytically derived using a geometric optical model. As a result, the relationship between the inner and outer element spacings in the proposed antenna model is expressed by a quadratic function. It was confirmed that the self-interference level can be reduced about 25 dB by setting the element spacings based on the theoretical formula. In addition, we compare the achievable rate between the proposed method and HD(Half-duplex) scheme and show that the proposed method realizes the achievable rate up to 1.55-times higher than that of the HD scheme. |
