1. , a kind of data transferring method that is applied to ofdm system, in the different bandwidth data transfer unit, send comprise in the data transfer unit separately greater than 1 M OFDM symbol, wherein M is greater than 1, it is characterized in that the data transfer unit of each different bandwidth all transmits the OFDM symbol that has two kinds of different circulating prefix-lengths:

  • the OFDM symbol of the OFDM symbol of long loop prefix length and short circulating prefix-length;

    And in the different data transfer unit of bandwidth, transmit the OFDM symbol of the short circulating prefix-length of the OFDM symbol of long loop prefix length of similar number and similar number.
