In order to improve the performance of the conventional CMA blind equalizer a dual mode asymmetric constellation system is proposed. The adaptation of the equalizer eight coefficients changes from the standard algorithm to the dual mode algorithm depending on the error level. In this article the proposed technique is applied to a 4 QAM received signal corrupted by an additive Gaussian noise. Depicted results show that the performance for the cases under consideration appreciably dominates the conventional
