<p>A CDMA signal transmission power control method for appropriately compensating for a trouble of a transmission amplifying apparatus and a characteristic degradation thereof caused by distortion, without degrading the modulation performance, at occurrence of an instantaneous power during a channel signal multiplexing, or in an excess output state of transmission power caused by a trouble of the system. An amplitude value calculating part (13) determines a transmission power from amplitude information of a multiplex-combined signal. When the determined transmission power is equal to or greater than a first threshold value, the amplitude limitation of an amplitude limiting part (6) is canceled, and the gain of a variable amplifier (11) is controlled. When the determined transmission power is less than a second threshold value, the amplitude limitation of the amplitude limiting part (6) and the gain of the variable amplifier (11) are caused to return to their respective initial set values.</p> |
