基于模因算法的多模盲均衡算法
Multi-modulus Blind Equalization Algorithm Based on Memetic Algorithm
摘要
Abstract
Due to the slow convergence speed ,large mean square error(MSE) and existing blind phase for the constant modulus blind equalization algorithm (CMA) ,a multi‐modulus blind equalization algorithm based on memetic algorithm (MA‐MMA) is proposed .In this algorithm ,the reciprocal of the cost func‐tion of multi‐modulus blind equalization algorithm (MMA) is defined as the fitness function of the memet‐ic algorithm (MA) .The solution vector of individual in the whole group is regarded as the initial weight vector of MMA .The vector of the individual in whole groups corresponding to the fitness function maxi‐mum is searched by the global information sharing mechanism and local depth search ability of MA and used as the initial optimum weight vector of MMA .After the weight vector of MMA is updated ,the op‐timal weight vector of MMA is obtained .Simulation results prove that compared with CMA ,MMA . The multi‐modulus blind equalization algorithm based on genetic algorithm (GA‐MMA) which has re‐cently been proposed ,the proposed MA‐MMA has the fastest convergence speed ,the smallest MSE ,and the clearest constellations of output signals .关键词
