A multi-band orthogonal frequency division multiplexing (OFDM) system transmits the same symbol at least two times, and a receiving end can receive transmission data from a transmitting end accurately even when an error occurs from a wireless resource used by the multi-band OFDM system. To this end, the multi-band OFDM system has a transmitting end which selects one among at least three symbols being repetitively transmitted at least two times, and transmits the selected symbol by using different wireless resources so that the selected symbol is not consecutively transmitted, and a receiving end which receives the symbols from the transmitting end.
