This invention relates to methods for data transmission in OFDM (Orthogonal Frequency Division Multiplexed) communication systems. More particularly, it relates to data transmission in multi-band OFDM (MB-OFDM) systems. The method of generating an OFDM signal for transmission, comprises the steps of: dividing a plurality of subcarriers into two or more groups of subcarriers, minimising the peak-average power ratio (PAPR) of an OFDM signal, and enhancing the transmission of said OFDM signal by further repeating transmission of said OFDM signal.
