A base station system of a multicarrier CDMA and a data transmission method and a mobile communication system using the same are disclosed. The system includes a base station control apparatus connecting with an exchange, a pilot signal modulation apparatus for generating a spread spectrum modulated pilot signals as many as the number of carriers in accordance with a control of the base station control apparatus, a paging signal modulation apparatus for generating a spread spectrum modulated paging signals as many as the number of carriers in accordance with a control of the base station control apparatus, a plurality of traffic signal modulation apparatuses for generating a spread spectrum modulated traffic signals as many as the number of carriers in accordance with a control of the base station control apparatus, a plurality of combiners provided as many as the number of the carriers for combining input signals from the modulation apparatuses, and a radio frequency transmission apparatus for modulating the outputs from the combiners into multiple radio frequencies and transmitting the same, for thereby controlling a lot number of mobile stations by distinguishing the mobile station signals using an orthogonal codes at a link from a base station to a terminal in the multicarrier CDMA cellular system and removing a interference between the mobile stations in the same cell.
