A communication device is provided that includes a modulation circuit configured to modulate a signal comprising a first signal portion of a first data type and a second signal portion of a second data type. The modulation circuit is configured to modulate the first signal portion in accordance with a first modulation scheme and the second signal portion in accordance with a second modulation scheme. At least one of the first data type is different from the second data type or the second modulation scheme is different from the first modulation scheme. The communication device further includes a modification circuit configured to modify the modulated first signal portion based on a first modification scheme and the second signal portion based on a second modification scheme. The communication device further includes a transmitter configured to transmit the modified first signal portion and the modified second signal portion.
