Patent ID: 8885686

Claim:
A power line communication (PLC) device adapted for transmitting data symbols on a plurality of sub-carriers via a first transmission channel and a second transmission channel, comprising: transmitter circuitry configured to transmit signals over a PLC network, the PLC network including multiple wired transmission paths for transmitting the data symbols on the plurality of sub-carriers via the first transmission channel and the second transmission channel, and the transmitter circuitry including a demultiplexer circuit configured to receive an input bit stream and to provide a first and a second split bit stream, wherein continuous sequences of consecutive bits of the input bit stream are alternately allocated to the first and the second split bit streams; a first symbol mapper circuit configured to map bits included in the first split bit stream to first data symbols for the sub-carriers of the first transmission channel of the multiple wired transmission paths of the PLC network; and a second symbol mapper circuit configured to map bits included in the second split bit stream to second data symbols for the sub-carriers of the second transmission channel of the multiple wired transmission paths of the PLC network, wherein first and second data symbols assigned to a corresponding sub-carrier of the first and second transmission channels represent a continuous bit sequence in the input bit stream.
