광대역 전력선통신을 위한 채널모델링과 고속데이터 전송특성분석 = Analysis of Channel Modeling and High Speed Data Transmission Channels for Broadband Power-Line Communication

국문 초록 (Abstract)

본 논문에서는 복잡한 다중경로를 갖는 가정 전력선에 대한 채널 모델을 분석적 방법으로 전달함수를 분석하였다. 전력선의 배경잡음을 고려한 채널 모델 전달함수를 OFDM 시스템에 적용하였으며, QPSK 및 16-QAM 변조신호에 대한 BER 관계를 분석하였다. 광대역 전력선 통신시스템에 대한 OFDM 변조의 이득 관계를 제시함으로서 OFDM을 적용한 특성 파라미터를 예측할 수 있다.

In this paper, an analytic transfer channel modeling function by impulse signal propagation effects in indoor power-line network are analysed. The modeled channel parameters of power line channel including background noise is applied to the OFDM system and we analysis BER for QPSK and 16-QAM modulation signals with simulation. By the representation of gain for OFDM modulation, we can estimate the characteristic parameters of OFDM in Broadband power line communication.
