Distortion compensating apparatus, wireless communicating apparatus, and distortion compensating method |
摘要 |
A distortion compensating apparatus includes following units. An information measuring unit measures a distortion component and an electric power component based on a radiation signal. A compensation coefficient calculating unit calculates a compensation coefficient based on the distortion component and the electric power component. A signal transmitting unit outputs a signal corrected by the compensation coefficient as a transmission signal. A signal converting unit converts the transmission signal into a high frequency signal. An amplitude separating unit amplifies the high frequency signal and separates a portion thereof as a signal to be fed back. A feeding-back unit processes the portion and outputs the result as a feedback signal to the information measuring unit. An electric power information extracting unit outputs a portion of the high frequency signal as the radiation signal, extracts electric power information from the radiation signal, and directly outputs the electric power information to the information measuring unit.
