Quasi-Newton Constant Modulus Algorithm Based on Fractional Lower-Order Statistics for Blind Equalization
Qiu Tian-shuang · Jisuanji fangzhen · 2009
A new quasi-Newton constant modulus algorithm based on fractional lower-order statistics(QNFLOS_CMA) for migration of intersymbol interference(ISI) was introduced.This algorithm results in the performance enhancement of convergence speed than that of the constant modulus algorithm based on fractional lower-order statistics(FLOS_CMA),by the exploitation of Hessian information within the weight update equation.Simulations support the improved convergence properties of the new algorithm.
