Now that the constant modulus blind equalization algorithm is not sensitive to phase change of received signals in the electromagnetic spectrum fading channel,the modified constant modulus algorithm has been studied,which carries the amplitude information of received signals,also carrying the received signal phase information at the same time. In this paper,the modified constant modulus algorithm was deduced. Using the electromagnetic spectrum fading channel,performance of MCMA was simulated for higher-order QAM signals. Simulation has shown that MCMA not only greatly improved the degree of convergence of constellation after equilibrium,and corrected phase deflection.The algorithm can improve the convergence rate and reduce the residual intersymbol interference( ISI),accordingly improve the performance of the equalizer.
