An ultra wide-band (UWB) communication is used for medical information communication technology (MICT) as a dependable and safe communication technology. On the other hand, there are existing UWB systems that are not used for MICT. Generally these UWB systems use almost the same frequency band. Therefore they interfere to each other. In previous study, multiple access scheme using orthogonal pulse is proposed as a inter user interference free communication scheme. In this paper, we propose a mitigation method for inter-user interference and inter-system interference using combination of orthogonal pulse shape and orthogonal matched filter (OMF). The purposes of our system are; detect all signals of users in same UWB system; and reduce the unknown interference from other UWB system at the same time. The simulation results showed that the proposed system could detect the signals that were transmitted from same UWB system using orthogonal pulse set. Moreover, the proposed system could reduce the interference from unknown UWB system at the same time. |
