Abstract:
1. A multicarrier data modulation method, comprising: allocating a plurality of data bit signals of a serial input data stream among a plurality of carrier signals, wherein the plurality of data signals are modulated over the plurality of carrier signals by a modulation apparatus, wherein a predetermined number of the plurality of data bit signals are included in each one of a plurality of error correction symbols, wherein a number of the plurality of data bit signals modulated on at least one carrier signal is fewer than the predetermined number of data bit signals included in each of the plurality of error correction symbols, wherein each of said plurality of carrier signals is associated with a respective transmission channel, and wherein the allocating of the plurality of data bit signals among the carrier signals reduces a number of carrier signals that modulate data bit signals belonging to different error correction symbols during a transmission period.
