    • A nonlinear compensator comprising a signal processing section, a distortion detecting section, and a distortion correcting section. The signal processing section detects the time difference and phase difference between two signals by calculating correlation, synchronizes the two signals with each other, and causes the phase of one signal to coincide with that of the other. The distortion detecting section determines an amplitude error and a phase error in the two signals and inputs the errors as distortion components to a distortion correcting section. The distortion correcting section sequentially selects the amplitude, the phase, and the amount of compensation corresponding to the value of the amplitude from the amounts of compensation registered at the initial stage and updated adaptively, and adds the amount of compensation to the digital base band signal obtained at the input demodulation section to compensate for the distortion components.
    • 一种非线性补偿器,包括信号处理部分,失真检测部分和失真校正部分。 信号处理部分通过计算相关性来检测两个信号之间的时间差和相位差,使两个信号彼此同步,并且使一个信号的相位与另一个信号的相位一致。 失真检测部分确定两个信号中的振幅误差和相位误差,并将误差作为失真分量输入到失真校正部分。 失真校正部分从初始阶段登记的补偿量顺序地选择对应于振幅值的幅度,相位和补偿量,并自适应地更新,并将补偿量加到数字基带信号 在输入解调部分获得以补偿失真分量。
