The present invention relates to a weight processing technique suitable for multi-channel transmission in a wireless LAN (WLAN) system. To this end, a multi-channel transmitter includes a weight processor receiving an output signal, on which subcarrier rearrangement has been performed in a fast Fourier transformer, so as to simultaneously perform a power gain control function required for constantly maintaining an average power level, per subcarrier, which can be changed by channel bonding, and an antenna weight processing function for obtaining a diversity gain, thereby having simple implementation and an effect of improving transmission performance while being suitable for the standard of supporting multi-channel transmission. |
