Abstract
In this paper, we design a novel preprocessor involving signal selection and blind pose estimation such that our previously proposed iterative weighted least-mean-square (IWLMS) blind equalization algorithm only for BPSK and QPSK signals can be adopted for any arbitrary PSK signal constellation. The simulation results show that our proposed new BPE-IWLMS method greatly outperforms the conventional constant-modulus algorithm (CMA).
