A new dual-mode approach to blind equalization of QAM signals

摘要

The dual-mode CMA-assisted decision adjusted modulus algorithm (CADAMA) has been proved to be a very effective way of equalizing non-minimum phase channels blindly [Axford RA, et al., 1996]. However, it still suffers from a slow convergence when applies to the higher order QAMS. In this paper, we propose a new dual mode method for blind equalization of QAM signals, which achieves a faster convergence compared to the CADAMA. The simulation results show the better convergence rate of the proposed algorithm.
