Abstract:
1. A multicarrier Multiple Input Multiple Output (MIMO) Power Line Communication (PLC) transmitter for transmitting multicarrier modulated signals over a PLC network comprising: demultiplexer circuitry configured to receive an input bit stream and to generate first and second split bit streams, wherein continuous sequences of consecutive bits of the input bit stream are alternately allocated to the first and second split bit streams; mapper circuitry configured to generate first and second symbol streams based on the first and second split bit streams, respectively, the first and second symbol streams being associated with first and second transmission channels, respectively, the first symbol stream comprising a plurality of first data symbols, each first data symbol being attributed to a different carrier of a plurality of carriers, the second symbol stream comprising a plurality of second data symbols, each second data symbol being attributed to a different carrier of the plurality of carriers, and the first and second data symbols attributed to a same carrier of the plurality of carriers representing a continuous bit sequence in the input bit stream; precoder circuitry configured to apply MIMO precoding to the first and second symbol streams and generate first and second precoded symbol streams respectively; and multicarrier modulator circuitry configured to generate at least two multicarrier modulated signals based on the first and second precoded symbol streams; and at least two transmit ports configured to transmit the at least two multicarrier modulated signals via different combinations of wires in the PLC network.
