The accuracy of proposed MUSIC spectrum based localization is given in these figures with two different RIS patterns. From the results, we can find that the proposal can provide the coarse location information of the interference source. In addition, the localization of Y-axis is higher than that of X-axis because ULA of BS is parallel to the Y-axis which has large spatial resolution. However, RIS pattern seems to have not large impact on the localization performance and interference detection. The main reason is that the RIS pattern only aims to change the link powers between the BS and UEs but not for the detection of interference source. |
