摘要 针对信道的线性和非线性失真,在分析简化的非线性滤波的基础上,利用判决反馈的结构特点对其进行扩展,提出了基于UKF滤波的判决反馈均衡器,仿真表明,UKF滤波算法能降低系统均方误差性能。 Based on analysis of simplified nonlinear filter, aiming at linear and nonlinear distortions of the channel, extended decision feedback equalizer （DFE） with characteristics of DFE＇ structure is given. Based on the UKF filtering, a decision feedback equalizer is proposed. Simulation shows that the UKF filtering algorithm can reduce mean square error performance of the system.
