针对载波频偏和I/Q不平衡，提出了一种新的导频辅助补偿方案。该方案包括一个广义周期导频和一个低复杂度的获取算法，其中CFO和I/Q不平衡补偿系数可以以显式封闭形式获得。
We propose a novel pilot-aided compensation scheme for carrier frequency offset (CFO) and I/Q imbalance. The proposed scheme comprises a generalized periodic pilot and a low-complexity acquisition algorithm, where the CFO and the coefficients for I/Q imbalance compensation can be obtained in explicit closed-form.
