To solve the problem of large steady state residual error of momentum constant modulus algorithm(CMA)blind equalization,a momentum CMA blind equalization con-trolled by energy steady state was proposed.The energy of the equalizer weights is estimated during the updating process.According to the adaptive filtering theory,the energy of the equalizer weights reach to the steady state after the algorithm is converged,and then the momentum can be set to 0 when the energy change rate less than the threshold,which can avoid the additional gradient noise caused by momentum and further improve the conver-gence precision of the algorithm.
