| 摘 要： | 采用对称—反对称变换原理,提出了一种基于复数系统三、二阶归一化累积量盲均衡算法,克服了对称信号三阶累积量为零而无法进行信道均衡的缺点。计算机仿真表明,该算法实现简单,收敛效果好,稳态剩余误差小,其性能优于已有的一些同类算法。

| Abstract: | A novel third-second order normalized cumulant blind equalization algorithm in QAM system based on Symmetric-to-Asymmetric Transformation(SAT) has been brought forward.The defect has been overcome in this paper,which channel equalization can be not directly applied because the third order cumulant of symmetrically distributed signal is zero.Simulation results show that the proposed algorithm has better performances with low complexity,fast convergence and small steady residual error than the same algorithm. |
