s: A high performance blind adaptive multi-user detection algorithm is proposed by introducing U-D factor Kalman filter to estimate the optimal decision vector of CDMA multiple-user receiver. This algorithm can converge rapidly, tracking in high accuracy with satisfactory numeric stability. Simulation results show that this algorithm can eliminate multiple access interference (MAI) efficiently and is robust for numerical calculation.
