【摘要】 在信道眼图闭合的情况下,目前常用的均衡方法是使用常数模CMA等盲均衡算法来使眼图睁开,然后再切换到DD-LMS。本文对CMA+DD-LMS的切换条件进行了修改,引入了一个迭代阈值,以提高算法的收敛速度。计算机仿真结果证明了改进算法在性能方面的提高。更多还原

【Abstract】 When the channel eye diagram is close, the method of using blind equalization algorithm such as CMA to open the eyeand then switch to DD-LMS is often used. In this paper, a n iteration threshold is introduced to the switch conditionbetween CMA and DD-LMS in order to improve the algorithm’s convergence rate. The modified algorithm’s advantageis proved by computer simulation at last.更多还原
