%X Blind multiuser detection in multipath fading channel is an interesting topic in code division multiple access systems. In this paper a blind adaptive multiuser detector based on Minimum Mean Square Error (MMSE) criterion is proposed. In order to guarantee that the algorithm converges to the desired user, a new linear constraint technique that limits the searching space is developed. The new constraint can guarantee that the algorithm converges to the global MMSE optimal solution. Besides, an efficient iterative implementation that provides very fast convergence is proposed. Simulation results show the efficiency of the proposed algorithm.
