基于可变步长的常数模盲均衡算法
Blind equalization algorithm based on variable step-size
摘要
Abstract
In order to overcome the slow convergence rates and large error rate in constant modulus algorithm, a novel blind equalization algorithm based on variable step size is proposed in this paper to obtain better equalizing results. A new non-liner function is established based on relationship between step size, and then the function is used to adjust step size of the equalizer which has faster convergence and smaller equalization error, the simulation experiment is carried out to test the performance. The results show that compared with the traditional algorithm, the proposed algorithm can accelerate the convergence speed, greatly reduces the residual error rate, and has good application value.关键词
