For a non-minimum phase system, the interaction of the system is viewed as measurable disturbance and decoupled using feedforward strategy. 针对非最小相位系统，将系统的耦合作用视为可测干扰，采用前馈方法予以消除。
However real channels are generally non-minimum phase systems, baud-spaced equalizers exhibit poor performance under this circumstance. 同时由于实际信道往往为非最小相位系统，此时线性均衡器性能不佳。
