1. A data transmission method used in a radio system comprising at least one base station (1) and a subscriber terminal (2-4) which modulate a signal to be transmitted on subcarriers of an orthogonal multicarrier modulation and transmit a reference signal (6-8) in a band in use by using reference carriers formed by the multicarrier modulation, characterized in thatthe reference carriers are substantially randomly placed in the band in use;

  • the reference carriers have a reference number; and

    the reference carriers are placed in the band in use by using a linear congruential generation formula based on iteration;
