초록

최근 차량내 무선통신이 자동차 산업에서 큰 관심을 받고 있으며 UWB 기술이 차량내 통신 시스템에 유력한 기술로 고려되고 있다. 차량내 통신 채널의 측정과 모델링에 대한 많은 연구가 이루어져 왔으나, 차량내 통신환경에서 다양한 PHY Layer 기술에 대한 성능 분석은 여전히 많은 관심의 대상이 되고 있다. 본 논문의 목적은 차량내 채널환경에서 IEEE 802.15.4a PHY 시스템의 성능을 분석함에 있다. 새시와 엔진 부분의 채널 모델을 설정하고, 동기식 및 비동기식 수신기의 성능을 시뮬레이션을 통하여 분석하였다.

Recently wireless intra-vehicle communication has received a great interest from the automotive industry and ultra wideband (UWB) technology is considered as one of the potential candidate for this system. Many research works have been done on the measurement and modeling of intra-vehicle communication channel. However, very little work has been reported for the performance analysis of various PHY layer methods under the intra-vehicle communication environment. This paper is to study IEEE 802.15.4a standard in intra-vehicle channel and to evaluate its performance. Channel model in chassis and engine compartment is considered for evaluation. Through simulation BER performance of system with different receiver structures is analyzed.
