Abstract
A pre-processing least squares constant modulus blind multiuser detection algorithm, based on decision-feedback (PDF-LSCMA), in an antenna array system is proposed in this paper. The robustness of PDF-LSCMA to the DOA estimation error and the maximum value of DOA estimation error are also analyzed in this paper. Simulation validates the algorithm and theoretical analysis.
