Abstract :
A variable step size blind equalization algorithm based on minimum error probability (MEP) was proposed. The cost function based on minimum error probability was founded. And the iterative equations of the variable step size blind equalization algorithm were deduced by the steepest gradient. Simulations demonstrate that the novel proposed algorithm possessed faster convergence and smaller steady MSE than MEP algorithm.
