심장 박동기, 캡슐 내시경 등 의료용 임플란트 분야의 무선 통신 장치는 의료 시스템 개선을 위해 연구 개발되어 왔습니다. 특히 각 장치의 범위와 위치를 아는 것은 전송 전력의 최적화에 기여하므로 매우 중요합니다. 우리는 초광대역 신호를 사용하여 위치 추정에 시간 기반 접근 방식을 채택합니다. 그러나 인체 내부의 전파 속도는 조직마다, 주파수마다 다릅니다. 또한, 인체는 다양한 조직과 복잡한 구조로 이루어져 있습니다. 이러한 이유로 인체 내부의 지점마다 전파 속도가 다르며 수신된 신호는 인체 내부의 채널을 통해 왜곡됩니다. 본 논문에서는 송신기와 수신기 사이의 상관기 출력을 기반으로 전파 시간을 정확하게 계산하기 위해 다중 경로 채널에 적응형 템플릿 합성 방법을 적용합니다. 또한, 인체 내부의 전파 속도 추정을 이용한 위치 추정 방법을 제안한다. 또한, 제안 방법이 약 캡슐과 같은 의료용 이식 장치의 크기에 따라 정확한 위치 결정을 수행할 수 있음을 컴퓨터 시뮬레이션을 통해 보여줍니다.

Abstract: Wireless communication devices in the field of medical implant, such as cardiac pacemakers and capsule endoscopes, have been studied and developed to improve healthcare systems. Especially it is very important to know the range and position of each device because it will contribute to an optimization of the transmission power. We adopt the time-based approach of position estimation using ultra wideband signals. However, the propagation velocity inside the human body differs in each tissue and each frequency. Furthermore, the human body is formed of various tissues with complex structures. For this reason, propagation velocity is different at a different point inside human body and the received signal so distorted through the channel inside human body. In this paper, we apply an adaptive template synthesis method in multipath channel for calculate the propagation time accurately based on the output of the correlator between the transmitter and the receiver. Furthermore, we propose a position estimation method using an estimation of the propagation velocity inside the human body. In addition, we show by computer simulation that the proposal method can perform accurate positioning with a size of medical implanted devices such as a medicine capsule.
