Abstract :
A new variable step size blind equalization algorithm based on a variable step size blind equalization algorithm in which step size is controlled by auto correlative error signal pointing to problems lie in limiting constant step size blind equalization algorithm, which momentum term is introduced and momentum term weighted parameter is adjusted by step size. The new algorithm which has a fast convergence and higher stability can equalize the channel better by theoretical analysis and simulations.
