Predistortion linearizer and predistortion distortion compensation method, program, and medium |
摘要 |
A predistortion linearizer has signal dividing means of dividing an input signal into two signals; signal adjusting means of using one of the divided signals to execute predetermined adjustment and outputting a signal based on the adjustment; distortion signal generating means of generating a distortion signal using the signal output from the signal adjusting means; signal synthesizing means of synthesizing the other of the divided signals with the generated distortion signal; and signal amplifying means of amplifying the synthesized signal and outputting an output signal, and wherein the signal adjusting means executes the predetermined adjustment such that there is a predetermined relationship between the level of a difference between the signal amplitudes of predetermined frequency components contained in a distortion signal and the level of a difference between the signal amplitudes of the predetermined frequency components contained in a distortion signal.
