【Abstract】 A robust blind linear multi-user detector based on a robust Capon beamforming technique is proposed.The amount of diagonal loading to control the robustness can be precisely determined according to the given uncertainty set of signature waveform.Theoretical analysis and simulation results show that the presented method exhibits improved performance on bit error rate and asymptotic multi-user efficiency.Moreover,it is not difficult to deduce its adaptive version by appropriate adaptive eigen-decomposition tracking algorithms.multi-user detection;DS-CDMA;multiple access interference;beamforming;robustness更多还原
