Bit-level repetition is applied to at least a portion of the PDU to create a repeated portion. Interleaving is performed per a subchannel. Pilot tones are inserted in the interleaved portion. Each data tone is modulated with respect to a nearest one of the inserted pilot tones. The PDU is transmitted over a power line.
