In the view of bad communication environment for the quality of power line communication , to advance the research of transport technology, this paper designed a power line remote communication system based on OFDM. Introduced the transport of OFDM based on FFT and Wavelet in detail. and comparing their the rate and efficiency with each other in data transport,thus making PC visualization monitoring in real time possible by using LabVIEW. Making a primary research on the inspection approach of PLC. The results reflect that the whole system behaves well and is able to achieve quick and steady PLC communications in data transport resistanceStoSinterference and security etc.
