Abstract:
The present invention relates to a method for allocating subcarriers in an orthogonal frequency division multiplex (OFDM) system, and a transmitter thereof. In the OFDM system according to an exemplary embodiment of the present invention, the subcarrier allocation is performed in the buffer (10) before a modulation mapping operation is performed according to a modulation method such that the delay may not be generated in the subchannel formed on the symbol axis. The delay corresponding to the symbols is prevented without using any additional hardware for eliminating the delay generated when the subcarriers are allocated to the subchannel formed on the symbol axis.
