The blind algorithm based on Parzen windows method PDF has a better performance then CMA.Similarly to CMA,this algorithm has a stochastic phase rotation phenomena.Through the phase information of the MAP criterion,a concurrent soft decision-directed blind equalization algorithm based on Parzen window method PDF(PPDF+SDD) was studied.Simulation for high-order quadrature amplitude modulation(QAM) shows that the proposed algorithm improves the equalizer performance by offering faster convergence and smaller misadjustment.Furthermore,the proposed algorithm overcomes the stochastic phase rotation phenomena.
