Abstract:
A distortion compensation apparatus for compensating for distortion occurring in an amplifier, said distortion compensation apparatus comprising:distortion generating means for generating distortion of one of an amplitude and a phase of a signal provided for the amplifier; signal level detecting means for detecting a level of the signal provided for the amplifier; distortion amount control means for controlling an amount of the distortion generated by said distortion generating means based on the level detected by said signal level detecting means; and control timing adjusting means for adjusting a timing for controlling the amount of the distortion by said distortion amount control means to adjust a delay time between a timing of the generating of the distortion of the signal by said distortion generating means and the timing of the controlling based on the level of the signal by said distortion amount control means, so that a residual amount of distortion due to a presence of the delay time in the signal issued from the amplifier is minimized.
