在本文中，我们提出了一种通用相位旋转共轭消除（PRCC）方案，用于正交频分复用（OFDM）系统中的载波间干扰（ICI）消除。结果表明，先前的共轭消除（CQ）方案相当于我们提出的方案的特例。一般的 PRCC 方案包含传统 CC 方案的优点，例如与现有 OFDM 系统的向后兼容性、低接收器复杂度和两路径分集，但提供了更好的性能，特别是在高频率偏移情况下。
In this paper, we propose a general phase rotated conjugate cancellation (PRCC) scheme for intercarrier interference (ICI) cancellation in orthogonal frequency division multiplexing (OFDM) systems. It is shown that the previous conjugate cancellation (CQ scheme is equivalent to a special case of our proposed scheme. The general PRCC scheme contains advantages of the conventional CC scheme, such as backward compatibility with the existing OFDM systems, low receiver complexity, and two-path diversity, but provides better performance, especially at high frequency offset situations.
