摘要: 针对现有盲均衡技术收敛速度慢、稳态误差大、容易收敛到局部极小值的缺点,文中提出了基于小生境遗传优化的正交小波变换盲均衡算法.该算法利用小生境遗传算法搜寻全局,并利用正交小波盲均衡提高收敛速度.计算机仿真结果验证了算法的有效性.Abstract: In order to overcome the slow convergence rate and large steady state error of present blind equalization, a new Blind Equalization Algorithm Based on Niched Genetic Algorithm and Wavelet Transform (NGAWT-CMA) was proposed.The proposed algorithm utilizes NGA to globally search and uses wavelet transform to improve convergence rate.The results of computer simulation proved the validity of the algorithm.
