description PROBLEM TO BE SOLVED: To provide a method of transmitting multicarrier data which can increase an efficiency of a system in multicarrier data transmission. SOLUTION: The method of transmitting multicarrier data includes: a step A to preselect candidate phase sequences having low correlativity from a unit circle in a coordinate space, to process transmission queue data in a transmission side using the preselected phase sequences, to calculate PAPR values of the processing result and compare them with each other, and to determine a candidate phase sequence corresponding to the minimum PAPR value to be a selected phase sequence; a step B to set a signal obtained by multiplying a transmission signal by the selected phase sequence to main information, and to transmit the signal to a receiving side together with a group number of the selected phase sequence; and a step C to determine the selected phase sequence based on the received group number in the receiving side, and to reconstruct the received main information to form the transmission queue data.
