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