UWB 시스템 기반 다중안테나 송신 다이버시티를 이용한 거리측정 정확도 향상 기법

In this paper, we propose an UWB (Ultra Wideband) ranging system by using MIMO transmit diversity for high accuracy under LOS (line of sight) environment. The proposed system uses an Alamouti space time code scheme with transmit diversity and DS-UWB approach based on impulse radio transmission. Simulation results have shown that the proposed system has better performance than conventional schemes, since it can utilize the good properties of spatial diversity.
