Abstract
A sub-carrier diversity method on an MB-OFDM (multi-band orthogonal-frequency-division-multiplexing) system repeatedly transmitting an identical frequency band of an identical symbol, including: setting a value of a TDS (time domain spreading) of sub-carriers depending on a transmission rate; and shifting the positions of the sub-carriers in a predetermined unit so that the sub-carriers diverge from one band to another.
