    • Embodiments herein relate to a method in a transmitter (501) for enabling a transmission of a signal from the transmitter (12), wherein the transmitter (501) is an out-phasing transmitter. The transmitter (501) generates, in a signal separator (503), two signals with different phases and same amplitude from an input transmission signal. The transmitter (501) then amplifies a first signal of the two signals in a first power amplifier (505) in the transmitter (501 ), and a second signal of the two signals in a second power amplifier (506) in the transmitter (501). The transmitter (501) further obtains, for each of the two amplified signals, an indication of a phase distortion of respective signal of the two amplified signals, and provides, to the signal separator (503), phase distortion information, which is based on the obtained indications.
    • 这里的实施例涉及发射机(501)中的用于使得能够发送来自发射机(12)的信号的方法,其中发射机(501)是一个外相发射机。 发射机(501)在信号分离器(503)中产生具有来自输入传输信号的具有不同相位和相同幅度的两个信号。 发射机(501)然后放大发射机(501)中的第一功率放大器(505)中的两个信号的第一信号,并且在发射机(501)中的第二功率放大器(506)中的两个信号的第二信号 )。 发射机(501)还针对两个放大信号中的每一个获得两个放大信号的相应信号的相位失真的指示,并向信号分离器(503)提供基于 获得的迹象。
