Abstract: A blind multiuser detection algorithm based on nonlinear least squares method is proposed.It is proved that as the number of the sampled data vectors is large, the performance of this algorithm tends to the performance of MOE.Simulations indicate that the performance of this algorithm is better than that of CMOE, and can be used in variable enviorment.
