| 摘 要： | 为了解决传统的自适应均衡技术需发送训练序列的问题,采用盲均衡技术,利用接收信号本身的特征使均衡器收敛。提出了一种新的盲均衡算法(C&D算法),该算法将CRIMNO算法和判决引导(Decision Directed,DD)算法相结合,利用信号序列间的互不相关特性,从而使其具有全局收敛性能。实验结果表明:与CRIMNO算法相比,在相同的信噪比下,该算法具有收敛快速、运算量少和残留误差小的特点。

| Abstract: | In order to solve the problem that traditional adaptive equalization technology needs to transmit training sequences,using blind equalization technology,the equalizer converges by making use of characteristics of received signal.A new blind equalization algorithm(C&D algorithm) is proposed in this paper.The algorithm combines the CRIMNO algorithm and the Decision Directed (DD) algorithm,and makes use of irrelevance among signal sequences,so that it has global convergence.The experimental results show that,c... |
