Abstract

To use the power line as the communication channel, we have analyzed channel characteristics with the noise data and signal attenuation levels measured on power lines per loom. In this paper, channel capacities are calculated in the best or the worst case noise states and signal attenuations on power lines for three kinds of network-topologies. Analyzed the channel capacity by the best and worst conditions, we concluded that the serious factors influenceing on the channel capacity are the length from a transmitter to a receiver and the network topology.

통신을 위한 채널로써 전력선을 활용하기 위해서, 전력선상에서 존재하는 잡음을 측정하여 잡음 데이터를 획득하고, 망구조에 따른 단위길이(100m당)에 따른 신호 감쇄량을 측정했다. 본 논문에서 구분한 3종류의 전력선 구조에 따른 신호 감쇄와 잡음의 최대, 최소값을 이용해서 채널 용량식에 대입한 후 통신 채널로써 전력선이 가지는 채널용량을 계산하였다. 건물내 전력선이 가지는 채널용량은 전력선에 있어서 송,수신기 사이의 거리와 전력선 망구조에 영향을 크게 받는 것으로 나타났다.
