Conventional blind equalization algorithms suffer from ill convergence to local minima and slow convergence speed.This paper proposes a novel blind equalization algorithm.using random search methods evolution strategies and existing cost functions. Simulation results verify the fast and global convergence of the proposed algorithm.
