In a transmission power control unit for use in a transmitting apparatus, power control amount correctors (111, 112, 11N) carry out, on the basis of detected signals, correction of power control amounts on transmission amplitude data to produce corrected data. A power control correction code generator (14) generates a power control correction code. Spreading sections (161, 162, 16N) carry out spread processings on the corrected data using replaced spreading codes into which respective parts of spreading codes are replaced with the power control correction code. A multiplexer (19A) multiplexes spread data into a multiplexed amplitude datum. A D/A converter (21) converts the multiplexed amplitude datum into an analog signal. A radio section (23) carries out modulation, frequency conversion, and power amplification on the analog signal to produce a transmission signal. A distributor (25) extracts a part from the transmission signal as an extracted signal. A frequency converter (29) converts the extracted signal into a frequency-converted signal. A despreading section (31A) carries out a despread operation on the frequency-converted signal to detect transmission power for the respective channels. A timing controller (33A) generates a clock signal for synchronizing the despreading section and the spreading sections. <IMAGE> |
