ABSTRACT:
A nonlinear compensating circuit, a base-station apparatus and a transmission power clipping method for executing a clipping operation in a high output amplifier at the transmitting end during multicarrier amplification. A plurality of power converting circuits calculate power values of respective input signals. An adder adds up the calculated power values to obtain a synthetic power value P. A divider divides a predetermined threshold value T by the synthetic power value P. When the divided value T/P is equal to or more than 1, a determining circuit outputs a clip control signal for turning off the clipping operation to a plurality of clipping circuits. When the divided value T/P is less than 1, the clip control signal turn on the clipping operation.
