摘要
本文采用信道评估标准ＣＥＳ（ＣｈａｎｎｅｌＥｓｔｉｍａｔｉｏｎＳｔａｎｄａｒｄ），基于信道输出信号的三、四阶累积量，构成了一种实现ＣＥＳ盲均衡的方法。该算法具有较快的收敛速度，运算量与ＢＧ法相近，不受加性高斯分布白噪声影响。文中给出了ＱＡＭ信号计算机仿真实验结果。
In this paper,we present a CES(Channel Estimation Standard )-type blind equalization algorithm based on the 3th- and 4th-order cumulants of the channel output.Avoiding the large amount computations that often occur in the CES-type blind equalizations,it has faster convergence speed and better MSE and SER(Symbol Error Rate)performances compared with BG algorithm.It's insensitive to the additive Gaussian white noise,The simulation results are given for nonminimum phase linear channel using QAM signals.
