A new global fractionally spaced blind equalization approach based on the use of pattern search optimization and two new constant modulus fourth order asymmetrical modulations schemes is proposed. Simulation results in terms of intersymbol interference and a new performance measure show that the proposed approach achieves perfect global convergence behavior together with correction of the random phase rotation of the constellation. The propagation environment is a frequency selective channel in the presence of Gaussian noise.
