WIRELESS TRANSMISSION APPARATUS AND DISTORTION COMPENSATION METHOD |
| 摘要 |
A wireless transmission apparatus includes an amplifier that amplifies power of a multicarrier signal, a first frequency shift unit that performs a first frequency shift on a first signal fed back from the amplifier on the basis of carrier frequencies of the multicarrier signal to output a second signal after the first frequency shift, a band limiting unit that performs frequency band limitation on the second signal to output a third signal after the frequency band limitation, and a distortion compensation device that compensates nonlinear distortion of the amplifier on the basis of the third signal. |

1. A wireless transmission apparatus comprising:
an amplifier that amplifies power of a multicarrier signal; a first frequency shift unit that performs a first frequency shift on a first signal fed back from the amplifier on the basis of carrier frequencies of the multicarrier signal to output a second signal after the first frequency shift; a band limiting unit that performs frequency band limitation on the second signal to output a third signal after the frequency band limitation; and a distortion compensation device that compensates nonlinear distortion of the amplifier on the basis of the third signal. |
