This invention is a multiple access service to terminals which filter the transmission signal transmitted through the multi-tone filter that the multi-carrier consisting of a base station based on the radio communication system that provides each terminal multiplexer and outputting a plurality of transmission signals by multiplexing the input signals, at least one filter bank for filtering the plurality of transmission signals, The Fourier filter the filtered transmission signal output from the inverse Fourier transform to the bank converter, and comprises a filter information generator for providing filter information to the filter bank. Transmitter in accordance with the present invention does not require a user-to-user uplink synchronization process which is a problem in a particular multi-carrier-based communication system, so as to identify the user of the filter can be expected to improve system performance.
