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.

6. A receiver comprising:
-
a receiving unit receiving N symbols that are generated by combining N data signals and are mapped to subcarriers that are spaced more than a coherent bandwidth apart; a subcarrier de-allocating unit moving the N symbols, which are mapped to the subcarriers that are spaced more than a coherent bandwidth apart, to their own original positions; and a data separating unit separating N pieces of data from the N symbols, which are moved to their own positions and demodulating the N pieces of data. - View Dependent Claims (7, 8, 9)

11. A method of transmitting and receiving data in a system for transmitting and receiving data using a frequency diversity scheme, the method comprising:
-
combining N data signals received from an encoded bit stream to generate N symbols; mapping the N symbols to subcarriers that are spaced more than a coherent bandwidth apart; receiving and moving the N symbols, which are mapped to the subcarriers that are spaced more than a coherent bandwidth apart, to their own positions; and separating N pieces of data from the N symbols, which are moved to their own positions, and demodulating the N pieces of data.
