Interference aid frequency offset estimation for user equipment

A frequency offset estimation system, user equipment, and a communication system are provided. The frequency offset estimation system comprises a first frequency offset estimator to estimate wanted signal frequency offset of a wanted signal in an input signal; a second frequency offset estimator to estimate interferer frequency offset of an interferer in the input signal; and a frequency offset estimation combiner to generate a combined frequency offset estimation by combining estimates of the wanted signal frequency offset and the interferer frequency offset. 提供了频率偏移估计系统、用户设备和通信系统。频率偏移估计系统包括：第频率偏移估计器，用以估计输入信号中的有用信号的有用信号频率偏移；第二频率偏移估计器，用以估计输入信号中的干扰源的干扰源频率偏移；以及频率偏移估计组合器，用以通过将所述有用信号频率偏移和所述干扰源频率偏移的估计进行组合来生成组合频率偏移估计。
