| Abstract(in English) | We focus on the coexistence environment of UWB (Ultra Wideband) system and 4G system. Because UWB systems occupying wideband, UWB is required to reduce an influence on existing wireless communications systems. Therefore, UWB is obligated to equip Detection and Avoidance technology (DAA) for the 4th generations of Mobile systems (4G), WiMAX and so on. We focus on the Integrated terminals composed by 4G system and UWB system which enables the communication from the suffer side to the inflict side. 4G determines permissible suffered interference based on desired SINR of 4G system and current SNR and broadcast permissible transmission power to close-range UWB terminals. As a result, UWB can achieve optimal transmission power control (TPC) by comprehending the state of 4G which is suffered system. |
