摘要：
An apparatus and method are provided that compensates for the problematic time-varying DC offset by effectively eliminating a near-channel amplited modulated interferer from a signal. The apparatus includes a first channel estimator for estimating a plurality of first channel filter taps null using a first signal model St, and a second channel estimator for estimating a plurality of second channel filter taps {tilde over (H)} using a second signal model {tilde over (S)}t. The apparatus also includes a processor for selecting which of the first signal model St and the second signal model {tilde over (S)}t is to be used or was used to substantially eliminate the near-channel amplitude modulated interferer from the received signal. The apparatus can be a mobile phone, base station, direct conversion receiver, or communications system (for example).
摘要（中）：
提供了一种通过有效地消除信号中的近通道放大调制干扰源来补偿有问题的时变DC偏移的装置和方法。 该装置包括：第一信道估计器，用于使用第一信号模型St估计多个第一信道滤波器抽头H;以及第二信道估计器，用于使用第二信号模型St估计多个第二信道滤波器抽头H.该装置还包括 用于选择第一信号模型St和第二信号模型St中的哪一个将被使用或用于基本上从接收信号中消除近通道幅度调制干扰源的处理器。 该装置可以是移动电话，基站，直接转换接收机或通信系统（例如）。
