Embodiment Construction
[0022] Taking the domestic 220V / 50Hz low-voltage power line as the application object, the implementation method of the present invention will be described in detail in conjunction with the accompanying drawings and typical embodiments, but the scope of the present invention is not limited in any way.
[0023] Such as figure 1 As shown, the power line communication system using pulse modulation of the present invention includes a digital baseband signal processor 1 , a pulse generator 2 , a transmitting path 5 , a receiving path 11 , a coupler 6 and a power line 7 .
[0024] In more detail, the digital baseband signal processor 1 includes a transmitting unit 12 and a receiving unit 13 . Wherein, the transmitting unit 12 is connected with the pulse generator 2 , maps the original binary data into a corresponding digital signal, and transmits it to the pulse generator 2 . The receiving unit 13 is connected to the receiving path 11, and is used for processing the digital signal ...
