| 摘 要： | 介绍了一种全新的设计盲均衡器的评估标准──信道评估标准ＣＥＳ（ＣｈａｎｎｅｌＥｓｔｉｍａｔｉｏｎＳｔａｎｄａｒｄ），并就其实现方式作了简要讨论，在分析现有算法优缺点的基础上，基于高阶统计量，对非最小相位线性信道，提出了一种ＣＥＳ型盲均衡算法ＨＣＢＥＡ，该方法避免了ＣＥＳ盲均衡中常见的大运算量的缺陷，由多电平ＰＡＭ及ＱＡＭ信号仿真实验表明，该方法具有良好的均衡特性。

| Abstract: | In this paper, a new concept of channel estimation standard (CES) is introduced and its realization methods are discussed simply. Based on the higher-order cumulants, we proposed a CES type blind equalization algorithm (HCBEA) for linear nonminimum phase communication system. The method avoids the large amount of computation that often occurs in the CES type blind equalization. The computer simulation results show that this algorithm is effective. |
