Claim:
1. A transmitting apparatus comprising: a modulating circuit configured to generate a plurality of sets of symbols, which include a first set of first symbols and a second set of second symbols, from a bit sequence, each of the first symbols including the same bits included in a corresponding one of the second symbols; a orthogonal frequency division multiplexing (OFDM) circuit configured to map the first set of first symbols and the second set of the second symbols onto a plurality of subcarriers in a frequency domain to generate a multicarrier signal, the first set of first symbols and the second set of second symbols being mutually exclusive in the frequency domain; and a radio frequency (RF) transmitter configured to transmit the multicarrier signal, wherein the modulating circuit is further configured to generate N/M sets of symbols, wherein M is a first number of bits per symbol in a first transmission scheme and N is a second number of bits per symbol in a second transmission scheme, and N/M is a positive integer greater than one.
