To minimize phase distortion, keep the path lengths the same. 为了最小化相位失真，请保持通路长度的一致。
Based on fractional sampling method, a new super-exponential iteration decision feedback blind equalization algorithm for severely nonlinear phase distortion channels was proposed. 因此针对严重频率衰落和非线性相位失真信道，提出了一种分数采样的混合盲均衡算法，并获得了较快的收敛速度和较小的剩余均方误差。
