Inbound communications using electricity distribution network |
摘要 |
Signals carried inbound on an electricity distribution network are detected by extracting electrical current information from a waveform of the electricity distribution network, and digitally filtering the electrical current information, thereby forming a digital waveform, to extract signal information contained in the electrical current information. A reference waveform is constructed from a portion of the digital waveform, and the signal information is detected by comparing portions of the digital waveform with corresponding portions of the reference waveform.
