Abstract: Provided are a transmitter and a receiver. The transmitter combines N data signals received from an encoded bit stream to generate N symbols; maps the N symbols to subcarriers that are spaced more than a coherent bandwidth apart; and receives and moves the N symbols, which are mapped to the subcarriers that are spaced more than a coherent bandwidth apart, to their own positions. The receiver demodulates N pieces of data using the N symbols received from the transmitter in a manner similar to that used by the transmitter.
