A multi-carrier peak clipping module includes a power calculating unit, a multi-carrier power accumulating unit, a multi-carrier peak clipping determining unit, a peak clipping calculating unit and a power conversing unit. The multi-carrier peak clipping module carries out a peak clipping process to a non-main broadcast control channel (BCCH) carrier of the multi-carrier to obtain the output power clipped of each carrier in next slot according to the input power control information of each carrier in next slot, and then to obtain the power control information adjusted of each carrier in next slot. A multi-carrier control method and base station are also provided. Through the peak clipping process to the non-main BCCH carrier, not to the main BCCH carrier, the total output power of the multi-carrier high power amplifier can be decreased under the situation of the power over-configured, and the main devices are protected to operate reliably while a stable coverage of GSM network is formed, so as to ensure the stability of the performance of GSM network. |
