Abstract
A data transmission method for orthogonal frequency division multiplexing system, specifically comprises sending M, which is greater than 1, OFDM symbols included in each data transmission unit with different bandwidth, wherein each data transmission unit with different bandwidth sends two kinds of OFDM symbols with different cyclic prefix lengths: OFDM symbols with the long cyclic prefixes and OFDM symbols with the short cyclic prefixes; and the data transmission units with different bandwidths transmit the identical number of OFDM symbols with the long cyclic prefixes and the identical number of the OFDM symbols with the short cyclic prefixes.
