| Summary: | Novel technique to modulate the nulls in the radiation pattern of IMT-Advanced base station (BS) towards the fixed satellite service is (FSS) affirmed in this paper. Designing a new algorithm to extract the nulls in the forbidding area and other base on MUSIC algorithm to estimate the direction of mobile user and control the handover technique is our major concern. A scenario of two mobile users (MS) moving around one FSS had been exclusively studied and simulated. We are looking through the mechanical of interference and our ultimate goals is to develop mechanize for interference mitigation by deploying a special division multiple access technique SDMA with MU-MIMO base on OFDM. Calculating the shortest separation distance after identifying the critical point and compare the result with the recent recommendation had shown how magnificent coexistence and spectrum sharing we can get. Analysis, discussion and conclusion had been made to explain. |
