We proposed a dual mode CMA algorithm MCADAMA(modified CMA-assisted decision adjusted modulus algorithm),which is suitable for QAM signal.Inspired by the MCMA,based on the study of dual-mode CMA algorithm CADAMA proposed by Axford,we proposed and studied the MCADAMA algorithm and compared MCADAMA with other three CMA algorithms based on a blind equalization system of QAM.The simulation results showed that the MCADAMA has faster convergence rate and lower bit error rate,and can improve system performance effectively.
