선형 주기적 시변 전력선 채널의 측정 및 분석

Abstract

Indoor power-line channel response exhibits a time-varing behaviour with a two fold nature. The first one is the traditional long-term variation caused by the connection and disconnection of electrical devices. The second one is the short-term variation, synchronous to the mains, whose origin is the dependence of the impedance presented by electrical devices on the mains voltage. In this paper, a statistical analysis of cyclo-stationary channel properties obtained from a measurement campaign performed at different scenarios is given.
