| Summary: | 碩士 === 輔仁大學 === 電子工程學系 === 94 === The description of the thesis is the influence of appliances and artificial noise on power line communication. The interference produced by the load on the power line, such as electromagnetic interference, impedance matching etc. The data was gotten from network management system. The noise effects on the signal noise ratio, channel frequency response, up/down stream received power and up/down stream speed.
To compared the data from spectrum analyzer and network management system. The noise is measured by the spectrum analyzer trough the GPIB and power line broad band communication network. In conclusion, the most important thing is to overcome the high frequency noise and attenuation on the power line for the broad band communications. Finally, the most important thing is to set up the standard for power line communication.
