    • A method of compensating carrier tone generation between duty cycles includes receiving a carrier frequency signal and a reference frequency signal, where the carrier frequency signal is mixed with a communication signal in a signal path. The method includes determining a first and second time differences between the carrier frequency signal and the reference frequency signal at respective clock edges of the reference frequency signal. The method includes converting the first time difference to a first corresponding phase value and the second time difference to a second corresponding phase value based on an operating frequency, and determining a phase difference between the first corresponding phase value and the second corresponding phase value. In turn, the method includes adjusting the communication signal with the phase difference independent of the signal path to maintain phase continuity in the signal path between the duty cycles.
    • 在占空比之间补偿载波产生的方法包括接收载波频率信号和参考频率信号,其中载波频率信号与信号路径中的通信信号混合。 该方法包括在参考频率信号的各个时钟沿确定载波频率信号和参考频率信号之间的第一和第二时间差。 该方法包括基于工作频率将第一时间差转换为第一对应相位值和第二时间差到第二对应相位值,以及确定第一对应相位值和第二对应相位值之间的相位差。 反过来,该方法包括以独立于信号路径的相位差来调整通信信号,以维持占空比之间的信号路径中的相位连续性。
