碩士 === 輔仁大學 === 電子工程學系 === 95 === Power line communication is a technology which used the network of power line for the transmitting medium. It couples the modulated signals to power line network for transmitting the data and messages. The paper describes the influence of appliances and artificial noise on power line communication. The interference which interfere PLC system produced by the load on the power line, such as electromagnetic interference, impedance matching etc. The data was gotten from PLC network management system. The noise effects on the signal noise ratio, channel frequency response. The noise is measured by the network management system designed of power line broad band communication. To compared the results from the data which is transmitted by LabView. And, by simulating a power line communication network, the frequency response and the model of transmission channel are presented.
