Abstract
A transmission power control apparatus for outputting a transmission data to be filtered by a band-limiting filter (9), includes: a branching unit (81) for branching transmission data before being entered into the band-limiting filter (9); a peak detecting filter (84) having the same structure as that of the band-limiting filter (9), for entering thereinto one of the transmission data branched by this branching unit (81); units (85 to 89) for calculating a correction value capable of suppressing a power peak of the transmission data by being filtered by this peak detecting filter (84); a delaying unit for delaying the other data of the branched transmission data by time required to calculate the correction value; and a correcting unit (83) for correcting the transmission data delayed by this delaying unit (82) based upon the correction value, and thereafter, for entering the corrected transmission data into the band-limiting filter (9).
