摘要（英）：

The invention relates to an embedded type broadband power line carrier communication system based on OFDM modulation, and belongs to the technical field of power line carriers. The embedded type broadband power line carrier communication system based on OFDM modulation comprises an Ethernet component, a PLC modulation and demodulation component, a carrier signal coupling unit and a power adapter component. All the components are highly integrated on a printed circuit board and are connected in sequence. Due to the adoption of an OFDM modulation mechanism, the embedded type broadband power line carrier communication system based on OFDM modulation has the advantages of being capable of effectively overcoming intersymbol interference, high in capacity of resisting disturbance, utilization ratio of bandwidth and communication bandwidth, simple in balance and the like. Due to the adoption of the embedded type structure, the embedded type broadband power line carrier communication system based on OFDM modulation further has the advantages of being simple in structure, easy to expand, convenient to use, safe, reliable and the like.
