Abstract :
A novel affine projection blind equalization CMA algorithm is presented in this paper. Based on quantization estimation errors and variable step-size, the algorithm can enhance convergence speed and decrease steady-state errors. Meanwhile, the algorithm has lower hardware implementation complexity because of the use of quantization estimation errors. Simulation results show that the performance of the novel algorithm has obvious advantages in convergence speed and steady-state errors.
