New Hybrid Blind Equalization Algorithms

摘要：

　　A novel decision-directed Modified Constant Modulus Algorithm (DD-MCMA) was proposed firstly.Then a constellation matched error (CME) function was added to the cost function of DD-MCMA and CME-DD-MCMA algorithm was presented.Furthermore,we improve the CME-DD-MCMA by replacing the fixed step with variable step size,that is VSS-CME-DD-MCMA algorithm.The simulation results show that the proposed new blind equalization algorithms can tremendously accelerate the convergence speed and achieve lower residual inter-symbol interference (ISI) than MCMA,and among the three proposed algorithms,VSS-CME-DD-MCMA has the fastest convergence speed and the lowest residual ISI,but it has the largest computation complexity.
