摘　　要：研究了基于频域的几种非线性均衡器算法,对其在频域上的各种处理操作进行分析,并根据传输信道与信号格式的特点提出了一种改进的算法,利用频域双向迭代结构进行均衡处理。通过重新构建系统模型,并对加权系数和判决检测算法进行改进设计,降低了算法的复杂度,提高了算法灵活性。通过仿真和分析表明,当信道条件相近时,所述算法可以达到更优的均衡效果。Several nonlinear equalizer algorithms based on frequency domain are studied,various processing operations in frequency domain are analyzed,and an improved algorithm is proposed according to the characteristics of transmission channel and signal format,the structure is balanced.By rebuilding the system model and improving the design of the weighting coefficient and decision detection algorithm,the complexity of the algorithm is reduced and the flexibility of the algorithm is improved.Simulation and analysis show that when the channel conditions are similar,the algorithm can achieve better equalization effect.
