Abstract :
A multi-modulus blind equalization algorithm based on genetic algorithm is proposed in this paper. It combines the advantages of multi-mode blind equalization algorithm and decision directed algorithm, uses genetic algorithm to optimize the weight vector of equalizer and gets better balanced results. Theoretical analysis and computer simulations indicate that the proposed algorithm outperforms multi-modulus blind equalization algorithm in convergence rate and steady-state convergence residual.
