一种用于判决反馈均衡器的方法和装置，其中使用一校正项来补偿限制器误差，从而避免了误差传播。选择均衡器的滤波器系数以便使均衡器的代价函数最小-One for decision feedback equalizer method and device, which uses an error correction terms to compensate for the limiter, thus avoiding error propagation. Select equalizer equalizer filter coefficients so that the minimum cost function
